Abstract
A portable thermal power generation device generates power using heat produced by a living body. A thermal power generation member generates power on the basis of a temperature difference between a temperature at a heat source-side position and a temperature at a heat release destination-side position between the living body that is a heat source and a heat release destination of heat released from the portable thermal power generation device. A movable member is configured to change a thermal resistance of at least part of a heat transfer path between the living body and the heat release destination.
Claims20
A thermal power generation portable device configured to be mounted to a living body and capable of generating power with the heat of the living body, the thermal power generation portable device comprising:
- a thermal power generating member that generates power on the basis of a temperature difference between a temperature at a heat-source-side position and a temperature at a heat release destination-side position between the living body that is a heat source and a heat release destination of heat released from the thermal power generation portable device;
- and
- thermal resistance changing means for changing the thermal resistance of at least a portion of a heat transfer path between the living body and the heat release destination.
A power generation control method comprising:
- a first step of providing a thermal power generation portable device configured to be mounted to a living body and capable of generating power with the heat of the living body, the thermal power generation portable device comprising:
- a thermal power generating member that generates power on the basis of a temperature difference between a temperature at a heat-source-side position and a temperature at a heat release destination-side position between the living body that is a heat source and a heat release destination of heat released from the thermal power generation portable device;
- thermal resistance changing means for changing the thermal resistance of at least a portion of a heat transfer path between the living body and the heat release destination;
- and
- a second step of changing the thermal resistance of at least a portion of the heat transfer path during generation of power by the thermal power generating member;
- and
- a third step of changing, after the changing of the thermal resistance in the second step, the thermal resistance of at least a portion of the heat transfer path toward a value before changing of the thermal resistance in the second step.
