Soft Materials for Soft Robotics

Soft Material-Actuator

We have developed a unique self-contained, electrically-driven, soft, robust composite material-actuator that combines the elastic properties of a polymeric matrix and the extreme volume change accompanying liquid–vapor transition. The material combines a high strain (up to 900%) and correspondingly high stress (up to 1.3 MPa) with low density (0.84 g cm−3). Along with its extremely low cost (about 3 cents per gram), simplicity of fabrication, ability to be 3D-Printed, environment-friendliness, these properties could enable new kinds of electrically driven entirely soft robots. The research was published in Nature Communications.
