SYSTEMS AND METHODS FOR HARVESTING PIEZOELECTRIC ENERGY FROM HYDRAULIC PRESSURE FLUCTUATIONS

摘要

aspect of the present disclosure relate to systems and methods for obtaining the energy from the pressure ripple of a fluid system. In the exemplary embodiment, the system comprising: a housing; Fluid communication with the pressure ripple and piezoelectric stack configured in response to the pressure ripple characteristics to generate a piezoelectric voltage and current of a fluid system associated piezo-piezoelectric stack is disposed in the housing; And piezo-electric stack in electrical communication with and includes a control circuit configured to convert a DC voltage to the piezo-electric current. ;
