Bosselaar, Chris (author)<b>Background</b><br/>Rheumatoid arthritis (RA) is a progressive, chronic, inflammatory, autoimmune disorder, affecting 0.5-1.5% of the world's population. Current RA disease activity assessment methods rely on subjective, labor-intensive methods. Therefore, an unmet need exists for objectively assessing RA disease activity through a low-labor...master thesis 2024

van Wezel, Sterre (author)Running Specific Prostheses (RSPs) enable running for athletes with lower limb amputations. The RSP design is inspired by human ankle behaviour while running, aiming to replicate its dynamic properties. RSPs are produced using carbon fiber composites that exhibit elastic properties, allowing them to store and return energy. Unlike biological...master thesis 2024

van Zanten, Jonathan (author)Semi-active lower limb prostheses currently use variable damping to generate the gait cycle. This, however, only dissipates energy. Variable stiffness can store and release energy, making prostheses more efficient for walking. This study aims to design and evaluate a semi-active adjustable stiffness ankle-knee prosthesis that can change its...master thesis 2024

Smits, Jurriën (author)Energy harvesting has gained lots of interest over the past few decades. This study explores the application of energy harvesting in lower limb prosthetic devices. The control system of a lower limb prosthesis includes sensors, wireless<br/>systems and other active components which all require battery power. In order to save some of this battery...master thesis 2024

van der Plas, Anne-Marijn (author)Immobilisation devices are commonly used for the treatment of extra-articular distal radius fractures. However, conventional immobilisation devices such as plaster casts and fibreglass casts may lead to complications and discomfort. Another disadvantage of present-day conservative fracture treatment is that the casts have to be replaced after...master thesis 2023

Dijkstra, Mathijs (author)This thesis presents the conceptual development of an innovative parallel manipulator that leverages the beneficial attributes of parallel kinematic structures. These attributes include increased stiffness, uniform load distribution, and reduced moving mass, which are strategically incorporated into the design to enhance resource efficiency....master thesis 2023

Venkata Shanmukha Sreeramagiri, Souri (author)Energy dissipation plays a crucial role in mitigating noise and vibration in a wide range of applications. In the field of assistive devices, energy dissipation is used to improve the stability of joint motion and protect the musculoskeletal system from excessive loads. It is not surprising that considerable effort has gone into developing...master thesis 2023

De Boeck, Jan (author)In the context of prosthetic devices, the absence of natural sensory feedback poses a significant challenge, leading to limited proprioceptive sensation and reduced control over artificial limbs. This study explores the potential of establishing a magnetic connection between prosthetic devices and muscles to enhance proprioceptive feedback and...master thesis 2023

Joosen, Marnick (author)Spinal cord injury(SCI) is a life-altering event that often leads to wheelchair confinement and a lifetime of secondary health complications. Gait orthoses aim to restore mobility and improve the quality of life for these individuals. However, they are often rejected due to the high energy expenditure required by the individual. This project...master thesis 2023

van Delft, Youri (author)Background: Through technological development, a variety of mechanical finger joints have been produced. No current design takes inspiration from nature enough to develop a synovial inspired single finger joint. Due to this the potential performance is unknown, while natural joints out perform mechanical finger joints with respects to the...master thesis 2023

Brabander, Jesper (author)Automation within an industrial sector has now for years been an obvious factor. Everywhere mechanical instruments and sensors are implemented for fast and precise processes. The agricultural sector is some steps behind in relation to other sectors. Reason being that there are many irregularities which in other sectors have been made into...master thesis 2023

Brinkman, Anne (author)Background: The lack of access to electric powered wheelchairs for disabled people in low- and middle-income countries, that suit their rural environments, still remains an issue. Current available electric powered wheelchairs that do adapt to these rural environments are expensive and require complex control algorithms.<br/>Objective: The aim...master thesis 2023

van Hengel, Thomas (author)Goal: Build and evaluate the first prototype of the Cloud Walker, a passive assistive gait orthosis. Method: The Cloud Walker uses muscles of the upper body to store energy in the springs at the back of the Cloud Walker. This energy can than be used to swing the legs forward. The Cloud Walker was evaluated by 9 healthy participants walking on a...master thesis 2022

Drost, Sjoerd (author)Advantages of lightweight design robot links include cost savings and reduced energy consumption. The flexibility introduced by the lightweight design can cause structural vibrations decreasing precision. To mitigate this, an advanced controller is proposed, consisting of Iterative Learning Control combined with Full State Feedback control. To...master thesis 2022

Schijf, Menno (author)Introduction - Arthritis is a condition causing pain, deformations and loss of motion in human joints. The surgical instruments used to place a specific unconstrained prosthesis that is used to treat an arthritic joint are difficult to use. The objective for this thesis is to improve the current placement procedure by carrying out an analysis on...master thesis 2022

Verhage, Fabian (author)The Netherlands has a severe shortage of care workers. The shortage is expected to increase in the coming years. Care-robots could provide a solution, by taking work out of the hands of the care workers. The potential utility of the care-robot is dependent on the functionality of the gripper. The goal of this study was to design and develop a...master thesis 2021

Chung, Jeeyong (author)Background: Wrist immobilization orthosis is a commonly adopted treatment method for wrist regarding pathologies. In recent years, a group of 3D-printed immobilization orthosis for the upper extremity has been proposed. However, they were mainly developed as substitutes for traditional casts for the upper extremity for short-term usage. There...master thesis 2021
