Dielectric elastomer actuators (DEAs) are a promising soft actuator technology for robotics. Adding robotic functionalities--folding, variable stiffness, and adhesion--into their actuator design is a novel method to create functionalized robots with simpli ...
Modern wearable robots are not yet intelligent enough to fully satisfy the demands of endusers, as they lack the sensor fusion algorithms needed to provide optimal assistance and react quickly to perturbations or changes in user intentions. Sensor fusion a ...
This paper presents advances in the development of a microrobotic platform actuated by three liquid droplets in a gaseous environment (Drop-bot or Drobot). Drobot builds on the bubble robotics concept earlier introduced by Lenders [1]. A new platform desig ...
In the past couple of years, the concept of exosuits has emerged. These soft, robotic devices are primarily made of textiles and can be worn like clothes. They assist the user during specific motions by transmitting forces around the human joints making us ...
We designed a miniature multimodal actuator by combining servomotors and vibrators. The actuator is mainly designed to non-invasively deliver tactile information to human skin by high-frequency vibration and low-frequency pressures simultaneously. By utili ...
To be implemented at the industrial scale, any dielectric elastomer actuator (DEA) must demonstrate long term reliability. For this purpose, a novel and fast DEA aging setup for high cycle tests has been developed. It monitors the in-plane strain and the c ...
Thermally activated shape memory alloy (SMA) actuators are direct-driven and produce high power density with design versatility. However, beyond their linear actuation in spring forms there is little variety and their application in robotics is limited by ...

A one-step process for the synthesis of elastomers with high permittivity, excellent mechanical properties and increased electromechanical sensitivity is presented. It starts from a high molecular weight polymethylvinylsiloxane, P1, whose vinyl groups serv ...
Enabling individuals who are living with reduced mobility of the hand to utilize portable exoskeletons at home has the potential to deliver rehabilitation therapies with a greater intensity and relevance to activities of daily living. Various hand exoskele ...
Soft robotics may provide many advantages compared to traditional robotics approaches based on rigid materials, such as intrinsically safe physical human-robot interaction, efficient/stable locomotion, adaptive morphology, etc. The objective of this study ...
