Claim of US Patent No. 10,512,150

1. A plasma actuator system for reducing aerodynamic drag of a vehicle by discharging plasma, the system comprising: at least one pair of thin films configured to integrate into a pair of electrodes wherein each of the thin films of the pair of thin films is composed of a thin film piezo-electric material; a dielectric configured as an insulator region to separate each electrode integrated with the thin film piezo-electric material; and a power supply configured to deliver alternating current to each electrode to provide a high voltage output obtained by the thin film piezo-electric material integrated with the pair of electrodes wherein the high voltage output is about 10 kilovolts.
