Shape programmable multi-stable polymer actuators

Bekir Aksoy

Recent advances in soft actuators have enabled systems that are safer to interact with, better at handling fragile objects, able to produce complex shapes with fewer components. However, being inherently soft differs these actuators from their rigid counte ...

Fabrication of zipping electrostatic actuators incorporating inkjet-printed layers

Herbert Shea, Samuel Rosset, Giulio Grasso

Zipping electrostatic actuators operate by bending flexible electrodes using electrostatic forces. This principle allows the use of a wide range of dielectric and conductive materials. Additive Manufacturing (AM) techniques can be used to fabricate these a ...

Design and modelling of a tubular dielectric elastomer actuator with constrained radial displacement as a cardiac assist device

Yves Perriard, Yoan René Cyrille Civet, Armando Matthieu Walter, Jonathan André Jean-Marie Chavanne

In this paper, we propose an improvement of a dielectric elastomer actuator (DEA) based augmented aorta. The actuator is a multi-layered tubular DEA subject to the internal pressure of the blood. When activated in synchronisation with the heart, the DEA su ...

Influence of electric field, temperature, humidity, elastomer material, and encapsulation on the lifetime of dielectric elastomer actuators (DEAs) under DC actuation

Herbert Shea, Fabio Beco Albuquerque

We present the effect of electric field, temperature, humidity, type of elastomer material, and encapsulation on the lifetime of silicone-based dielectric elastomer actuators (DEAs) under DC electric fields. DEAs are promising soft actuators, but little ha ...
