1. An energy harvesting apparatus, for deployment on a vehicle, the apparatus comprising:
- a vehicle shock absorber, comprising;
a dust tube; and
a damper tube telescopically mounted within the dust tube and configured for oscillating translational movement with respect thereto;
a magnet fixedly coupled to one of the dust tube or the damper tube; and
a coil fixedly coupled to the other of the dust tube or the damper tube to achieve relative translational movement between the magnet and the coil inducing a current in the coil.

Abstract
An energy harvesting apparatus, for deployment on a vehicle, comprises a vehicle shock absorber including a dust tube, and a damper tube telescopically mounted within the dust tube and configured for oscillating translational movement with respect thereto. A magnet is fixedly coupled to one of the dust tube or the damper tube, and a coil is fixedly coupled to the other of the dust tube or the damper tube to achieve relative translational movement between the magnet and the coil to induce a current in the coil.
