DEA Self-discharge Characterization for Low Duty Cycle Applications

Yves Perriard, Yoan René Cyrille Civet, Thomas Guillaume Martinez, Stefania Maria Aliki Konstantinidi, Raphaël Johannes Charles Mottet

This publication presents the characterization of self discharging Dielectric Elastomer Actuators (DEAs) in order to give place to low duty cycle applications, during which a DEA must remain actuated for long periods of time. DEAs typically present a low c ...
