Abstract:
An energy harvesting apparatus, for deployment on a vehicle, comprises a shock absorber, including a dust tube assembly, a jounce bumper assembly mounted within the dust tube assembly at a first end thereof, and a damper tube mounted for telescopic movement through a second end of the dust tube, the jounce bumper assembly configured for impact with the damper tube. A piezoelectric device is coupled to the jounce bumper assembly.
