PLANETARY REGOLITH DUST EXPULSION FOR STRUCTURES AND SURFACES USING PIEZOELECTRIC ASSEMBLY INDUCED VIBRATION

Abstract: a system is provided including one or more piezoelectric assemblies, where the one or more piezoelectric assemblies include a plurality of piezoelectric transducers. the system includes amplifier circuitry coupled to the plurality of piezoelectric transducers and configured to provide an alternating-current (ac) voltage signal to one or more piezoelectric transducers of the plurality of piezoelectric transducers, based on a target configuration associated with removing regolith dust from a vehicle operable in a space environment. the one or more piezoelectric transducers are configured to vibrate based on a magnitude and a frequency of the ac voltage signal.
