System and Method for Harvesting Energy from Environmental Vibrations

Embodiments of the present invention provide a system and a method for increasing the harvested energy from a piezoelectric element exposed to environmental vibrations via a two-prong system. In a first prong, a cantilever beam is tapered and shaped so as to increase and provide an approximately uniform strain on and along the beam, thus resulting in increased voltage. In a second prong of the system and method, a voltage compensating circuit, when used with a voltage inversion circuit of the prior art, increases the harvested power by injecting current to the piezoelectric element after each voltage inversion so as to increase the voltage level.
