<P>PROBLEM TO BE SOLVED: To suppress reduction of power generation efficiency and secure desired power generation quantity in an attached state to a living body. <P>SOLUTION: A thermoelectric portable device 10 is attached to a living body and capable of generating electric power by the heat of the living body, and includes: a thermoelectric member 20 which generates electric power based on a temperature difference between temperature at a position closer to a heat source and temperature at a position closer to a heat radiation side in a space between the living body as the heat source and a destination of heat radiated from the thermoelectric portable device 10; and a heat conduction variable section 22 capable of changing thermal resistance of at least a part of heat transfer path between the living body and the destination of heat radiation. Heat transfer fluid 222 is encapsulated in a part of the inside of the heat conduction variable section 22, and the heat transfer fluid 222 moves in response to a posture of the heat conduction variable section 22. With this movement, thermal resistance of at least a part of the heat transfer path can be changed by changing presence of the heat transfer fluid to the heat transfer path. <P>COPYRIGHT: (C)2013,JPO&INPIT |
