Science Daily  March 15, 2023 Although robots driven by rigid actuators have demonstrated agile locomotion and manipulation, most of them lack animal-like robustness against unexpected damage. Dielectric elastomer actuators (DEAs), a class of muscle-like soft transducers, have enabled nimble aerial, terrestrial, and aquatic robotic locomotion. However, unlike muscles, DEAs suffer local dielectric breakdowns that often cause global device failure. Researchers at MIT developed DEAs that can endure more than 100 punctures while maintaining high bandwidth and power density sufficient for supporting energetically expensive locomotion such as flight. They fabricated electroluminescent DEAs for visualizing electrode connectivity under actuator damage. When the […]
