Abstract
An energy harvesting apparatus for deployment on a vehicle having a frame includes a spring assembly coupled to the frame and configured for compressions and extensions during vehicle travel. A piezoelectric device is mounted on the spring assembly for generating electrical energy in response to the strain imposed thereon. A rectifier is coupled to the piezoelectric device for converting AC electrical energy to DC.
