Abstract
An energy harvesting device includes a housing (2), a moveable device (12) disposed within the housing and including a first surface including a first material (15) and a second surface including a second material (17), wherein the moveable device is operable to move to bring the first and second surfaces together and apart to cause contact and separation between the first and second materials, a first strap (4) attached to the housing, a second strap (6) coupled to the moveable device, wherein movement of the second strap causes operation of the moveable device, and electronic circuitry (20) structured to harvest energy from the electrical charge generated by the contact between the first and second materials.
