What are Dielectric Elastomer Actuators (DEA) and Sensors

operating principle DEAIn contrast to actuators based on rigid materials such as silicon, actuators based on elastomers can have very large percentage displacements, often exceeding 100% elongation, enabling new possibilities in many fields including soft robotics, tunable optics, and cell manipulation.
