Abstract
An energy harvesting device configured to convert thermal energy into electrical energy includes a heat storage portion configured to store thermal energy, a thermoelectric element configured to eliminate a temperature difference between electrodes when converting thermal energy into electrical energy, and an insulating portion in contact with the heat storage portion and the thermoelectric element. The heat storage portion has insulating properties. The thermoelectric element includes a pair of electrodes having work functions different from each other, and an intermediate portion provided between the pair of electrodes. The thermoelectric element is provided in contact with the heat storage portion and is covered by the insulating portion.
