Electrohydraulic and Piezoelectric Based Energy Conversion System

An energy conversion device comprising:

• a. A hermetically sealed container capable of withstanding pressures generated during cavitation collapse in the range of 100 MPa to 1000 MPa, filled with a pressurized dielectric liquid, said container housing a geometric shape comprising:
• i. An external layer comprising a material capable of resisting deformation under high-pressure conditions, caused by the pressure waves, configured to maximize power output by preventing outward expansion of the piezoelectric material;
• ii. A central layer comprising a piezoelectric material having a high coupling factor, high density, and high dielectric constant;
• iii. Optional intermediate layers positioned between the external layer and the central layer, comprising a material with a tensile modulus similar to that of the piezoelectric material, said intermediate layers configured to protect the piezoelectric material from damage;
• and.
• iv. Optional internal layers positioned within the central piezoelectric layer, comprising a material with a tensile modulus similar to that of the piezoelectric material, said internal layers configured to protect the piezoelectric material from damage.
• b. A positive electrode and a negative electrode positioned within said chamber and connected to a high-voltage power source, said electrodes configured to generate cavitation within the dielectric liquid in proximity to the geometric shape;
• and.
• c. Power output cables connected to the piezoelectric material and configured to deliver electrical energy to a load.
