Patent ID: 8841822

Claim:
An electrical power generator comprising: a. At least one piezoelectric device, having a top surface and a bottom surface, securely fixed on said bottom surface and capable of providing an electrical output upon application of a mechanical force on said top surface; b. a hydraulic device having an input piston capable of displacing a liquid in a tubing when an input force is applied to said input piston, and an output piston, larger than said input piston, hydraulically coupled with said input piston through said liquid in said tubing, so that when said input force is applied to said input piston, said output piston generates an output compressive force larger than said input force; c. connecting means keeping secured and in proximity said output piston with said top surface of said at least one piezoelectric device so that said output piston applies said output compressive force to said at least one piezoelectric device when said input force is applied to said input piston, whereby said at least one piezoelectric device is compressed with larger than said input force when said input force is applied to said input piston, and thus capable of producing more electricity than if said at least one piezoelectric device were compressed with a force equal to said input force.
