US Patent 11713240 Cellular array electrostatic actuator

Illustrative embodiments provide an electrostatic actuator and methods of making and operating an electrostatic actuator. The electrostatic actuator comprises a framework and a plurality of electrodes. The framework comprises walls defining a plurality of cells forming an array of cells. The plurality of electrodes comprise an electrode in each cell in the plurality of cells. A gap separates the electrode in each cell from the walls of the cell. The framework is configured to contract in response to an electrical signal applied between the framework and the plurality of electrodes.
