Background: Pneumatic actuators are widely used in applications like (medical) robots, or prostheses. Pneumatic actuators require a complex manufacturing process and are produced in standardized dimensions to reduce costs. Over the last decade 3D-printing has emerged as a cost-effective and efficient production method in medical applications....

Air bearings are a vital component to high tech machines and have been in widespread use since the 1960s. They provide near frictionless motion, have high stiffness and a near infinite lifetime. When looking at existing literature the influence of the porosity on the dynamic characteristics has not been researched in depth. Especially when...

The focus of this project was the research and development of an affective social touch wearable. AffectiveAir uses pneumatic actuation on the shoulder to convey a library of haptic sensations. The goal was to overcome physical limitations in potential digital communication contexts, by a non-verbal, tactile, and possibly intimate social touch...

Focal laser ablation is a new, promising method to treat tumors. The current focal laser ablation approach is to insert an optical fiber into the patient using rigid needles. A side effect of this approach is that during the needle insertion, tissue damage occurs. The larger the diameter of the needle, the more tissue damage. If the diameter of...

Compliant mechanisms actuated by pneumatic loads are receiving increasing attention due to their direct applicability as soft robots that perform tasks using their flexible bodies. Using multiple materials to build them can further improve their performance and efficiency. Due to developments in additive manufacturing, the fabrication of...

Standing up using one leg is a challenging task for those with a transfemoral amputation, particularly for elderly users with a low activity level. Active prostheses are generally not accessible to this group and available passive prostheses do not support standing up. This article presents the design and evaluation of the “Energy Restoring...

Fluid-controlled actuators are widely used in lower limb prostheses. Most fluid-controlled actuators have valves integrated into the cylinder systems and require complex manufacturing steps, making these systems expensive. A cost-effective production method for these complex actuator valve systems is 3D-printing. The goal of this research is to...

In cardiovascular interventions, when steering catheters and especially robotic catheters, great care should be paid to prevent applying too large forces on the vessel walls as this could dislodge calcifications, induce scars or even cause perforation. To address this challenge, this paper presents a novel compliant motion control algorithm...

Shape-changing textile interfaces have the potential to create unique functions, expressions, and interactions in everyday artifacts. However, the technical expertise required to fabricate and interact with these interfaces limits designers from rapidly iterating through diverse textile expressions. This pictorial presents TEX(alive), a low...

Sitting comfort is an important factor for passengers in selecting cars, airlines, etc. This paper proposes a soft robotic module that can be integrated into the seat cushion to provide better comfort experiences to passengers. Building on rapid manufacturing technologies and a data-driven approach, the module can be controlled to sense the...

Mobile soft robots show great potential for exploration of unknown and hard to navigate environments. Sadly, most of these robots are currently being held back by their power sources and control systems. These components, which are usually quite heavy and bulky, need to be integrated before mobile soft robots can cut their tethers and explore...

<b>Background</b> Pneumatic actuators are widely used in applications like (medical) robots, or prosthetics. They require tight tolerances to keep them leakage-free. Over the last decade 3D-printing, or additive manufacturing, has emerged as a cost-effective production method in these applications.<br/><b>Objective</b> The goal of this research...

Developments in minimally invasive surgery such as natural orifice transluminal endoscopic surgery and single port laparoscopic surgery have pushed medical devices to be higher articulated and more dexterous. These surgery methods have proven to greatly decrease bleeding, scar tissue, hospital time, and cost. The procedures involve the...

Background Upper limb prostheses help people with an upper limb deficiency in performing activities of daily living. They can be divided into two categories; body-powered and externally powered prostheses. The advantage of body-powered prostheses is that they provide feedback to the user. The advantage of externally powered prostheses is the low...

Cephalopods (e.g. squids, octopuses, cuttlefish) are able to actively adapt their appearance in terms of color, texture or transparency. The goal of this project is to mimic this ability with a simple and mechanical solution and apply this technology to a product or environment. This resulted in a pneumatic mechanism which folds open after...

Lower limb exoskeletons enable paraplegic patients to stand-up and walk again. However, the weight and overall functional performance of the exoskeleton prevents them from being widely used. To reduce the weight and increase<br/>the performance, pneumatic actuators can be used as an alternative to the commonly used electromechanical actuators....

Catheters are increasingly being used to tackle problems in the cardiovascular system. However, positioning precision of the catheter tip is negatively affected by hysteresis. To ensure tissue damage due to imprecise positioning is avoided, hysteresis is to be understood and compensated for. This work investigates the feasibility to model...

Introduction: Almost 57 percent of above elbow amputees stop using their prosthesis. One of the main factors of non-wear is the high weight. Pneumatic actuation can be more lightweight than electronic actuation, and might therefore help with reducing the mass of a prosthesis and...

Hand prostheses commonly advertise on three main selling points: strength, speed and lightweight. Most conventional hand prostheses are only able to combine two of these three attributes. Therefore, combining all three attributes into a single device can result in a commercially attractive hand prosthesis. Another interesting point, particularly...
