Photobiomodulation (PBM) uses red and near-infrared light to stimulate biological processes in the body and has been associated with benefits including skin rejuvenation, pain relief and muscle recovery. As scientific evidence supporting PBM continues to grow, an increasing number of home-use products have become available. However, most require users to expose bare skin while remaining stationary for extended periods, limiting convenience and user adoption.
Sunshower addresses this challenge by integrating PBM into the daily shower routine. Existing Sunshower products use halogen infrared lamps, which provide a broad light spectrum and a pleasant warming sensation but also result in high energy consumption, elevated operating temperatures and bulky product dimensions. This thesis investigates how LED technology can replace halogen lamps while maintaining therapeutic effectiveness and improving sustainability, usability and product accessibility.
The result is the Sunshower Nova, a wall-mounted LED-based PBM device designed for use during a regular shower session. The product combines red and near-infrared LEDs to deliver a therapeutic light dose that is consistent with current scientific literature within a ten-minute treatment. To support effective use, the system provides real-time feedback on treatment duration and user distance, helping users achieve the intended dose. The product architecture consists of a thermally optimised housing, a modular LED assembly and an optical front cover that together enable a compact, energy-efficient and manufacturable design.
The final design was validated through engineering analyses, performance measurements, user evaluations and a life cycle assessment. Compared with the existing halogen-based Sunshower, the LED-based design significantly reduces energy consumption and environmental impact while maintaining therapeutic performance and improving installation flexibility. The project demonstrates that LED technology enables a new generation of integrated shower-based PBM devices that combine scientific effectiveness with a more sustainable and accessible user experience.

Short track speed skating is characterized by high velocities and close athlete interactions, resulting in frequent crashes and a substantial risk of injury. To mitigate injury severity, protective padding systems are installed around the ice rink; however, current evaluation methods insufficiently represent the complex interaction between athlete and padding. Existing standardized tests rely on simplified geometries and perpendicular impacts, leading to unrealistic pressure distributions and limited biomechanical relevance. This study aims to improve the realism of padding safety evaluation by developing a projectile that more accurately simulates the interaction between a short track speed skater and padding, while remaining compatible with the ICE-G1 on-site testing system.
A comprehensive theoretical framework was established, integrating foam mechanics, crash dynamics, injury mechanisms, and scaling principles. Foam behavior was analyzed using a mass-spring-–damper model, highlighting the importance of impact velocity, contact area, and geometry in determining deformation and energy absorption. To define representative crash conditions, a video analysis of 62 real-world short track incidents was conducted. Results show that the majority of crashes occur at velocities above 40 km/h, with impact angles predominantly between 35 and 55\textsuperscript{o}, and back-first impacts identified as the most frequent and representative scenario. Furthermore, impacts were found to occur primarily in the lower region of the padding, often involving a single padding element.
A key limitation of existing test methods was identified in the mismatch between mass and contact area, resulting in stress levels that are not representative of real athlete impacts. To address this, a scaling strategy was developed based on preserving the mass-to-contact-area ratio, ensuring comparable stress distributions within the padding. This led to the design of a scaled projectile that more closely mimics the geometry and loading characteristics of a skater during impact, which is shown below (left).
Experimental validation demonstrated that the redesigned projectile produces higher and likely more representative peak accelerations compared to current testing approaches, indicating improved simulation fidelity. The findings emphasize that accurate representation of contact geometry and mass distribution is essential for realistic padding evaluation. Additionally, there is a difference between moveable and traditional padding. As the current standardized test method (ISU drop test) is unable to test moveable padding, this highlights yet another flaw in the current standard. The proposed method provides a significant step toward more representative and reliable testing of safety of padding systems in short track speed skating, and offers a foundation for future improvements in both testing methodology and athlete safety. However, as sensor limitations were encountered during experimental validation, the exact differences between the redesigned projectile and the current standardized test method is unknown, and more testing is required. ...

Adaptive Venting in Hearing Aids
Design of a Manual-Driven RIC Venting Mechanism
Today’s hearing aids are more advanced than ever before. In addition to their primary function of selectively amplifying specific frequencies to improve speech intelligibility, modern devices increasingly suppress unwanted background noise and enable phone calls and music streaming via Bluetooth connectivity with smartphones.
Despite these advancements, hearing aids still require a trade-off between wearing comfort and acoustic performance. Soft, open-fit domes reduce the occlusion effect and improve wearing comfort and perceived sound naturalness. However, they allow low-frequency sound leakage, which negatively affects bass response during music streaming and reduces speech intelligibility in noisy environments. In contrast, closed systems enhance low-frequency amplification and noise control, but often cause discomfort due to occlusion.
The only commercialised product currently addressing this challenge is the Phonak ActiveVent, which automatically switches between open and closed vent states based on environmental sound analysis. Despite its innovative approach, the electronic miniature components required for the automated mechanism reduce cost-effectiveness and durability, while limiting user control. This graduation project addresses these limitations through the development of a more robust, user-friendly, manual open/closed venting mechanism for Receiver-in-Canal (RIC) hearing aids.
Through desk research, user interviews, iterative prototyping and testing, an innovative manual alternative was developed. Fugai, the final proposed concept, is a RIC hearing aid featuring a manual adaptive venting mechanism that allows users to actively control their listening experience across different acoustic environments. By integrating a manual mechanism rather than an automated one, the design enhances robustness and durability while improving cost efficiency. Providing direct user control further increases perceived reliability and usability.
As a result, Fugai presents an innovative RIC solution that balances user autonomy, ease of use, robustness and cost-effectiveness, without compromising acoustic performance. ...

Schiphol Airport is facing a growing challenge: enabling independent mobility for Passengers with Reduced Mobility (PRM) in an environment where the number of passengers increases and ongoing staff becomes more limited. Every day, over 2,500 PRM passengers rely on assistance services, a number that continues to grow by 15–20% annually. At the same time, there is a clear shift in expectations: more and more PRM travelers are seeking autonomy, flexibility, and clarity in their journey.
This graduation project identifies this tension as an opportunity to introduce innovative mobility solutions at Schiphol Airport.
The central question that emerged was: How can a service be designed that enables PRM passengers with light mobility restrictions to use a wheelchair independently at Schiphol, and how can this service be communicated clearly and attractively?
Following the Double Diamond design process, the project began by uncovering systemic barriers during the Discover phase: fragmented information, poorly located wheelchair stations, rigid assistance protocols, and a lack of autonomy for users wishing to travel independently. Furthermore, the current service landscape was found to fall short in meeting the diverse needs of users who vary in age, physical abilities, cultural background, and digital literacy.
In response, six design criteria were established during the Define phase to guide the solution:
- The service must support autonomy,
- Provide complete and timely information,
- Be universally accessible,
- Integrate seamlessly into the airport infrastructure,
- Be operationally reliable and well-managed, and
- Remain adaptable to external developments such as new technologies or changing regulations.
These criteria led to the development of a service model that incorporates the organizational structure, the communication approach, and the strategic positioning of facilities into the design of two core elements: an interactive navigation tool and a network of Service Hubs. Together, these tools enable users to independently access mobility support, receive real-time information, and navigate the airport with confidence.
Simultaneously, the model strengthens internal clarity around responsibilities, allows for scalability, and embeds the solution within the broader airport ecosystem. It is designed to be future-proof, providing space for external changes and growth in response to evolving technologies, policies, and user needs.
The proposed concept was validated through scenario testing and stakeholder collaboration. It proved not only feasible but also highly relevant to both passengers and the organization, forming a solid foundation for implementing a hybrid mobility strategy across the airport.
This project demonstrates how thoughtful, strategic design can support both operational efficiency and inclusive passenger experience. Schiphol takes a step forward in redefining airport accessibility, not as a luxury, but as a fundamental right for every traveler. ...

Towards a broader adoption of Mobility as a Commons in Amsterdam
A strategic roadmap for the seamless integration of Mobility as a Commons in Amsterdam
The capital of the Netherlands, Amsterdam, faces significant urban mobility challenges, including high parking pressure, limited urban space and growing social inequality in mobility access. The Smart Mobility Program of the Municipality of Amsterdam envisions a more accessible, sustainable and safe mobility system, which asks for a mobility transition. Shared mobility, an alternative to private car ownership, plays a key role in the transition. This graduation project, conducted in collaboration with the Smart Mobility Program, explores the potential and broader adoption of Mobility as a Commons (MaaC), a cooperative concept where residents collectively manage, own, and share vehicles. Based on the principles of Commons, MaaC offers a community-driven bottom-up approach to shared mobility that is affordable and accessible and contributes to social cohesion and sustainable resource management.
The project's goal is to design a human-centred strategy that drives the broader adoption and integration of MaaC by addressing the needs, motivations, and barriers of Amsterdam residents. While the current approach to MaaC primarily focuses on practical aspects such as insurance, permits, and parking, this research bridges the gap by adopting a human-centred approach to designing the strategic roadmap.
To understand what and how to design, research was conducted on Amsterdam’s mobility system, behavioural change, and cooperative sharing. Generative user research was conducted on residents’ needs, motivations and barriers ensuring a human-centred approach. The findings show that MaaC is a viable, feasible and desirable mobility for both the Municipality and its residents. It has the potential to be a valuable tool in Amsterdam’s mobility transition, addressing key challenges such as parking pressure, affordability and accessibility. However, barriers such as unfamiliarity, finances, organisational complexity, habitual mobility behaviour and attachments to private cars hinder broader adoption.
To address these challenges, the project studies four behavioural change theories to understand how to design for behaviour change and comprehend the complexity of the various contexts. In addition, user research on two neighbourhoods in Amsterdam provided valuable insights into the various residents’ needs, motivations and barriers. All these insights have been translated into six need-based personas that form the foundation of the human-centred design approach.
To guide the Municipality, a strategic roadmap is designed. It provides a structured, human-centred framework for stimulating broader adoption, focusing on key resident groups and tailored strategies for various contexts. The Diffusion of Innovation theory provided a framework for managing the complexity of the various residents, needs and attitudes. It helped integrate the various adopter segments through the need-based personas into the roadmap. Both early adopters of shared mobility and more hesitant resident groups are considered, demonstrating that MaaC can be successfully adopted in various contexts. The key learning is the role of the Municipality. The bottom-up approach of MaaC asks for the Municipality to take on the role of facilitator, supporter and collaborator.
By reducing reliance on private vehicles and offering affordable, accessible and community-driven mobility, MaaC has the potential to be an effective tool in Amsterdam’s mobility transition towards the envisioned sustainable city.

The project's goal is to design a human-centred strategy that drives the broader adoption and integration of MaaC by addressing the needs, motivations, and barriers of Amsterdam residents. While the current approach to MaaC primarily focuses on practical aspects such as insurance, permits, and parking, this research bridges the gap by adopting a human-centred approach to designing the strategic roadmap.
To understand what and how to design, research was conducted on Amsterdam’s mobility system, behavioural change, and cooperative sharing. Generative user research was conducted on residents’ needs, motivations and barriers ensuring a human-centred approach. The findings show that MaaC is a viable, feasible and desirable mobility for both the Municipality and its residents. It has the potential to be a valuable tool in Amsterdam’s mobility transition, addressing key challenges such as parking pressure, affordability and accessibility. However, barriers such as unfamiliarity, finances, organisational complexity, habitual mobility behaviour and attachments to private cars hinder broader adoption.
To address these challenges, the project studies four behavioural change theories to understand how to design for behaviour change and comprehend the complexity of the various contexts. In addition, user research on two neighbourhoods in Amsterdam provided valuable insights into the various residents’ needs, motivations and barriers. All these insights have been translated into six need-based personas that form the foundation of the human-centred design approach.
To guide the Municipality, a strategic roadmap is designed. It provides a structured, human-centred framework for stimulating broader adoption, focusing on key resident groups and tailored strategies for various contexts. The Diffusion of Innovation theory provided a framework for managing the complexity of the various residents, needs and attitudes. It helped integrate the various adopter segments through the need-based personas into the roadmap. Both early adopters of shared mobility and more hesitant resident groups are considered, demonstrating that MaaC can be successfully adopted in various contexts. The key learning is the role of the Municipality. The bottom-up approach of MaaC asks for the Municipality to take on the role of facilitator, supporter and collaborator.
By reducing reliance on private vehicles and offering affordable, accessible and community-driven mobility, MaaC has the potential to be an effective tool in Amsterdam’s mobility transition towards the envisioned sustainable city.

This thesis focuses on developing a centralized dishwashing service with the goal of reducing the amount of disposable tableware waste generated at Avinor Oslo Airport. Moreover, the project aims to help Avinor Oslo Airport achieve its objective of becoming a zero-waste airport by 2030.
The research process followed the Triple-diamond model, facilitating a structured approach through mainly three phases: Understand, Ideate, and Develop. The ‘Understand’ involves the study of the literature review, analysis of existing practices, field research, and stakeholder interviews to gain an understanding of the context. During the ‘Ideate’ phase three concepts were developed and evaluated through iterative testing and feedback. Finally, at the ‘Develop’ phase, the final concept, Green Circles, is developed. Green Circles is a centralised dishwashing service for reusable takeaway containers, that allows passengers to drop the containers at drop-off machines at the boarding gates and airport exists.
The implementation of Green Circles is expected to significantly reduce single-use tableware waste at Avinor Oslo Airport. The study highlights the importance of stakeholder engagement, convenient passenger experience, and efficient operational integration. Broader implications suggest that similar services could be adopted in other airports, contributing to the aviation industry’s sustainability efforts, such as those proposed by TULIPS. ...

The purpose of this project is to conduct an applied human factors engineering research on the operator interface unit to reimagine the human-machine interaction of EUV lithography machines.
The user research consists of interviews, observations, a survey, task analysis and incident report analysis. It highlights that the main OIU user groups are install engineers, field service engineers, upgrade engineers, and customer operators. The main differences between the user groups are that, from a machine perspective, the ASML users have infrequent, but long OIU-related use scenarios, and customer operators have more frequent, short OIU-related use scenarios. Additionally, the OIU use environment changes according to the type of user, the workspace around the OIU can be limiting, and the cleanroom can be a stressful environment to work in. Finally, results show that the majority of the users feel physical discomfort when using the OIU after a relatively short use duration.
The design analysis presents a selection of key results that each impact the selection of the following set of design criteria for the future human-machine interaction: Provide textual & pointing input, space for input tools, provide visual output, optimize work posture, use all around machine, mobile device workflow, keep pathways clear, quickly accessible, and ASML aesthetics.
The outcomes of the user research and the design analysis are developed into a design proposal by conducting research into technology advancements, adjacent industries, organizing brainstorm and co-creation sessions, and finally developing and choosing one concept to proceed with.
The proposal is a system applying AR headsets, customer control room advancements, and a new digital platform. It allows the OIU to be removed from the machine and allocates new employee tasks to enhance efficiency. AR headsets enable the engineer to access the machine directly, have real-time work procedures, hands-free gesture and voice control, and improved remote collaboration. The AR headsets and adapted user interface allow the user to access and execute software actions during hardware tasks in the cleanroom. Additionally, longer, software actions can effectively be performed from the control room. This new approach improves the employee work conditions, minimizes cleanroom presence, improves work efficiency, accuracy and safety.
The design proposal is a future vision and is expected to take about 10 years before fully developed. However, due to the urgent conclusions regarding current physical discomfort, it is recommended to pilot a short-term mobile workspace solution in addition to initiating the long-term vision development. ...

Personal Air Filter
A purpose-designed air purifier to reduce the spread of airborne transmissive diseases in offices
The COVID-19 pandemic has highlighted the importance of indoor air quality in preventing the spread of airborne transmissive diseases. Offices are some of the largest hotspots for disease transmission. To address this issue, a joint venture between FLEX/design and Euromate, called ‘X-Lair,’ aims to design an air purifier specifically targeting the reduction of airborne disease transmission.
This project focuses on developing an air purifier solution that not only effectively reduces the spread of airborne diseases but also considers user experience and implementation in office environments. While primarily designed for placement above desks, the proposed solution has the potential to be applicable in various contexts.
Extensive literature research, user tests, empirical studies, interviews, and mind- mapping techniques have been employed to explore the research domain, identify design drivers, and establish a list of requirements. An iterative design approach, including tests with smoke and computational fluid dynamic analysis, have guided key design decisions. Additional tools such as Midjourney and virtual reality have facilitated the elaboration and visualization of ideas in their intended environment.
The final design proposal of the Personal Air Filter features a suspended configuration above desks, providing a large capture area to effectively filter the user’s breath. Plume propagation is considered by locating the air intake at the edge of the hood. An integrated lamp ensures comfortable ambient lighting, enhancing the device’s aesthetic appeal in office settings and improving employee well-being. A user interface, including a smartphone application, allows for convenient control of ventilation speed and lighting intensity. Smart features like the ‘smart mode’ enable autonomous operation, while interconnectivity between multiple devices enhances overall effectiveness and reduces noise.
A functional prototype was developed to validate the device’s efficacy and user experience. Smoke tests demonstrated the Personal Air Filter’s effective smoke capture at both 100 and 200 m3/h, indicating the potential for downsizing the device without compromising its performance. Special attention should be paid, however, to ensure that the Personal Air Filter operates at an acceptable noise level below 45 dB, taking into consideration the need for a quiet and comfortable office environment. Furthermore, user tests emphasized the need for a smartphone application and adjustable height for the Personal Air Filter.
In summary, the design of the Personal Air Filter represents a significant advancement in improving indoor air quality and promoting the well-being of office employees. The Personal Air Filter has the potential to become a unique and effective solution for mitigating the spread of airborne transmissive diseases. ...

The design of a kitesurf harness that decreases discomfort while increasing performance
A kitesurf harness for Mystic Boarding
The objective of this thesis is to enhance existing harness designs, with a focus on reducing discomfort and enhancing overall performance.
The contextual analysis, literature review, and desktop research yielded crucial insights and identified areas of improvement. Supplementary interviews were conducted with the user group. Initially, anthropometric data was sourced from existing databases like DINED; however, it lacked specificity to kitesurfing and the stances taken during kitesurfing, and some measurements relevant to the design of a kitesurf harness were missing, such as the torso length. To address this, an analysis of individual scans was done, followed by 3D scans of persons in kitesurfing stances.
It was found that the main factors leading to discomfort are the movement of the harness on the body, the pressure on the ribs, and the lack of pressure distribution. The main design goals stated are improved pressure distribution within the variation of movements and body types.
The findings of this thesis offer valuable insights into the potential for enhancing kitesurfing harnesses in terms of comfort, safety, and overall performance. By taking into account both the engineering and ergonomic aspects, this research contributes to the ongoing evolution of kitesurfing equipment, catering to the diverse needs and preferences of kitesurfers.
The final design is a modular kitesurf harness increasing the repairability, maintainability and upgradeability. The project includes anthropometric design guidelines for a kitesurf harness and multiple prototypes to test the concept. Resulting in a set of recommendations and designs that the Mystic team can take into consideration in the future steps towards developing the ultimate harness.

To address this, an analysis of individual scans was done, followed by 3D scans of persons in kitesurfing stances.
It was found that the main factors leading to discomfort are the movement of the harness on the body, the pressure on the ribs, and the lack of pressure distribution. The main design goals stated are improved pressure distribution within the variation of movements and body types.
The findings of this thesis offer valuable insights into the potential for enhancing kitesurfing harnesses in terms of comfort, safety, and overall performance. By taking into account both the engineering and ergonomic aspects, this research contributes to the ongoing evolution of kitesurfing equipment, catering to the diverse needs and preferences of kitesurfers.
The final design is a modular kitesurf harness increasing the repairability, maintainability and upgradeability. The project includes anthropometric design guidelines for a kitesurf harness and multiple prototypes to test the concept. Resulting in a set of recommendations and designs that the Mystic team can take into consideration in the future steps towards developing the ultimate harness.
This graduation report describes the design of an ice cooled liquid circulation cooling vest for INUTEQ, a company specialized in personal cooling. The new design, the INUTEQ ICE, is made for warehouse and factory workers. They need cooling vests, because they work in large buildings with flat roofs. Large buildings cannot be cooled by air-conditioning anymore and the sun can heat them up to tropical temperatures. Additionally, the temperature may, in some cases, be increased by the production processes inside. Working in the heat can decrease productivity, performance, comfort and safety. The physical work these people perform also increases their chances of heat related illnesses such as: heat rash, heat cramps or heat exhaustion. In some cases, overheating can even lead to a heat stroke.
One of the solutions to cool people down is with cooling garments. The INUTEQ ICE is an improvement on traditional liquid circulation garments, which cool by running the water through silicone tubes. The new design makes use of open cell foam pads to increase the heat exchange between the cold water and the body. The developed cooling pad technology was found to have a nearly three times as high cooling capacity per unit area compared to liquid circulating cooling technology currently on the market. In the same experiment, the cooling capacity per unit area of the new pad technology was found to be similar to existing 6.5°C PCM packs and higher than 15°C and 21°C. The design has the potential to cool for longer than the 6.5°C PCM packs. Contrary to evaporation and air based cooling vest, the INUTEQ ICE is able to be used underneath enclosed clothing and in other high humid environments.
The project contained three phases, an analysis phase, a development phase and an evaluation phase. In the analysis phase, relevant information about cooling garments and the target group is gathered. This information is brought together in a list of requirements. In the development phase, the cooling pad technology is developed and the cooling method is defined. The development phase ends with the first concept of the INUTEQ ICE. In the evaluation phase, a working prototype was made and user tested in the appropriate context, which provided useful insights towards the final concept. The evaluation phase also contains the previously mentioned cooling capacity test and recommendations to continue the project.
The end result of the project is a promising final concept, with working prototype. The INUTEQ ICE has the potential to become a product that, in humid environments, performs better than alternative cooling garments. With further development it can be used by different target groups, not only factory and warehouse workers. It seems likely that a finished version of the INUTEQ ICE can add value to INUTEQ’s product range.

Clean Aircraft Lavatory
Design of a new concept
The subject of this thesis report is a new concept design recommendation for Zodiac Aerospace with respect to better hygiene and cleanliness in aircraft lavatories during long haul flights.An integrated design research approach is taken to solve the issue of poor hygienic behaviour in the lavatory. This includes an analysis of the current standards and practices surrounding aircraft lavatories, a review of existing products, an analysis of relevant stakeholders, observational research onboard active flights and finally a concept design which aims to improve passenger hygiene. Research indicates that the small form factor of the lavatory makes it challenging for passengers to behave in a hygienic manner. The new design emulates the cubicle based layout of public restrooms, where wash basins are shared. Each lavatory increases in size by removing their wash basins and situating them in the cabin, where they are shared by passengers. Provision of separate lavatories for men and women enables the use of urinals for men and additional space for women and passengers with reduced mobility. Aircraft lavatories can be kept clean on long haul flights by creating new lavatory services and layouts which expand the space within the lavatory. Airlines can improve passenger hygiene and therefore satisfaction by providing lavatories which are larger and cater to more specific needs, such as standing and sitting urination. The new design is also of benefit to the process of manufacture and maintenance as it simplifies the existing product significantly and reduces the time it takes to clean and disinfect the aircraft between flights.
