1. An energy harvesting device configured to be integrated into an item of clothing, comprising:
an insulated container, comprising:
an outer membrane comprising an outer surface and an inner surface, the outer surface being in contact with an external environment;an inner membrane, spaced apart from the outer membrane, having an outer surface and an inner surface;an outer cavity spaced between the outer membrane and the inner membrane;an aperture extending from the outer surface of the outer membrane to the inner surface of the outer membrane, the aperture configured to permit an ingress of air and water from the external environment into the outer cavity;an inner cavity encapsulated by the inner membrane; an outer heat exchanger extending through the inner membrane, the inner membrane sealed around at least a portion of the outer heat exchanger; a thermoelectric generator positioned within the inner cavity, the thermoelectric generator thermally-coupled to the outer heat exchanger at a first side and thermally-coupled to an inner heat exchanger at a second side; and an expandable membrane encapsulating a mass of phase-change material, at least a portion of the expandable membrane coupled to the inner heat exchanger, wherein the outer heat exchanger, the thermoelectric generator, and the inner heat exchanger are configured to allow bi-directional conduction of heat between the mass of phase-change material and the external environment, wherein the aperture is configured to allow water to enter into the outer cavity during a wash cycle as the item of clothing is laundered, and wherein the phase-change material is configured to store a portion of heat energy captured during a dryer cycle as the item of clothing is laundered. |
