Abstract
The present disclosure generally relates to electrical power generation from a piezoelectric material. A piezoelectric power generator assembly is disclosed including a housing, a piezoelectric transducer located in the housing, and a piston located in the housing, wherein the piezoelectric transducer is configured to generate an electrical charge when contacted by the piston. A piezoelectric power generator assembly is also disclosed including a housing comprising a flowline located within the housing and a piezoelectric transducer located in the housing and disposed about a perimeter of the flowline, wherein the piezoelectric transducer is configured to generate an electrical charge when contacted by a fluid contained in the flowline. A subsea drilling system is disclosed including a subsea blowout preventer stack and a piezoelectric power generator assembly for powering sensors on the blowout preventer stack configured to monitor characteristics of the stack.
