1. An energy harvesting generator comprising:
- at least one piezoelectric element disposed between a base element connected to a base structure and a stop;
a flexible element fixed at at least one end to the stop;
wherein a deflection of the flexible element results in a compression of the piezoelectric element between the stop and the base element.

Abstract
A method for harvesting energy from an input deflection. The method including: storing mechanical potential energy in at least one spring element resulting from an acceleration of a mass connected to the at least one spring element; transferring the stored potential energy to a flexible element to deflect the flexible element; and converting the deflection of the flexible element to electrical energy by compressing at least one piezoelectric element due to the deflection.
