Publication number: 20210025626Abstract: In an embodiment of the invention, the device comprises a bottom electrode on a substrate and a top electrode on a substrate separated by a fixed distance from each other. Semi-insulator layers with proper electrical conductivity are attached to the bottom and top electrodes. Disposed between the substrates is a flexible S-shaped polymer stack having electrode layers with one end of the stack attached to the top substrate and the other end in contact with the bottom substrate. When a voltage is applied between the stack and the electrode layer on the bottom substrate, the stack is induced by electrostatic force to deflect in a rolling wave-like motion.Type: ApplicationFiled: March 25, 2019Publication date: January 28, 2021Applicant: The Regents of the University of CaliforniaInventors: Qibing Pei, Rujun Ma, Ziyang Zhang
