Patent ID: 7977807

Claim:
A wearable device that generates electricity from human movement to provide electrical power for mobile electrical devices, comprising: one or more flowable substances, one or more passageways through which flowable substance flows, wherein these passageways are worn over at least some portion of the exterior of the human body, and wherein there are one or more flow-directing structures that affect the direction of the flow of the flowable substance through these passageways, wherein the one or more flow-directing structures are one-way valves, and wherein, as the body moves, the walls of the passageways intermittently compress, interacting with the one-way valves to pump the flowable substance into circulation; and one or more energy-converting members: wherein each energy-converting member converts energy from the flow of flowable substance into electricity; wherein this flow is between two or more passageways, or between segments of a single passageway, that are substantially the same distance from the body surface; and wherein movement of the human body, independent of contact with a support surface such as the ground or floor, moves the passageways which causes the flowable substance to drive the energy-converting member which generates electricity.
