A Robotic Testing Platform for Pipelined Discovery of Resilient Dielectric Elastomer Actuators. [PDF]

Adv Sci (Weinh)
This work introduces a robotic testing platform enabling high‐throughput, multi‐parameter lifetime mapping of linear dielectric elastomer actuators (DEAs). By integrating programmable high‐voltage control and automated electromechanical measurements, the system identifies material and operating conditions that double actuator lifetime.
