Abstract
Aspects of the present disclosure relate to systems and methods for harvesting energy from the pressure ripple of a fluid system. In an example embodiment, a system comprises a housing; a piezoelectric stack in fluid communication with a pressure ripple of a fluid system and configured to generate a piezoelectric voltage and an associated piezoelectric current in response to pressure ripple characteristics, wherein the piezoelectric stack is disposed within the housing; and regulatory circuitry in electrical communication with the piezoelectric stack and configured to convert the piezoelectric current into DC voltage.
