Trunk postural tracking of assistive soft pneumatic actuator belt

Jamie Paik, Matthew Aaron Robertson

Fiber-reinforced Soft Pneumatic Actuators (SPAs) are found in mobile robots, assistive wearable devices, and rehabilitative technologies. Being intrinsically compliant and readily manufacturable they are attractive for use where safety and customizability ...

Functional Soft Robotic Actuators Based on Dielectric Elastomers

Jun Shintake

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 ...

A novel fluid driven, foldable joint for Minimally Invasive Surgery

Alice Tonazzini

In minimally invasive surgery (MIS) the aspect of miniaturization is getting more and more demanding. On the other hand, it is also important to assure high stability and large actuation forces at the end effector. Here we present the design and the develo ...

Monolithic transparent 3D dielectrophoretic micro-actuator fabricated by femtosecond laser

Yves Bellouard, Tao Yang

We demonstrate a three-dimensional (3D) monolithic micro-actuator fabricated by non-ablative femtosecond laser micromachining and subsequent chemical etching. The actuating principle is based on dielectrophoresis. An analytical modeling of this actuation s ...

A Foldable Antagonistic Actuator

Dario Floreano, Herbert Shea, Samuel Rosset, Jun Shintake, Bryan Edward Schubert

We report on an actuator based on dielectric elastomers that is capable of antagonistic actuation and passive folding. This actuator enables foldability in robots with simple structures. Unlike other antagonistic dielectric elastomer devices, our concept u ...

Sensory Feedback for Prosthetic Hand Users

Christian Enz, Huaiqi Huang, Tao Li, Jörn Justiz

The proposed project targets the restoration of a natural sense of touch to persons using hand prostheses. Current myoelectrical upper limb prostheses normally lack tactile feedback, which limits their functionalities and user acceptance. This work propose ...
