Bio-lnspired dielectric elastomer actuator with AgNWs coated on carbon black electrode.
Bio-inspired dielectric elastomer actuators with AgNW-coated carbon black electrodes were developed in this study. The novel elastomer actuators show large in-plane deformations by electrical stimulation through the both electrodes. When a certain input voltage is applied to the elastomer electrode, the electrostatic force between cathode and anode electrodes compress the dielectric elastomer film, resulting large in in-plane direction deformation. The expanded area of the circular actuation device under 70 mV/m electric field was measured up to 50% due to a synergistic effect of highly conductive AgNW network and ultrahigh capacitance of carbon black electrodes.
