Title:
VERTICAL THERMOELECTRIC CONVERSION ELEMENT AND DEVICE WITH THERMOELECTRIC POWER GENERATION APPLICATION OR HEAT FLOW SENSOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/187347
Kind Code:
A1
Abstract:
Provided is a novel thermoelectric conversion element with which the thermoelectric power generated in a direction orthogonal to both a temperature gradient and the magnetization can be increased without changing the thermoelectric conversion characteristic of a magnetic material. The present invention is provided with: a thermoelectric layer 10 comprising a thermoelectric material exhibiting the Seebeck effect; a magnetic body layer 20 stacked on the thermoelectric layer 10, said magnetic body layer 20 being conductive and the magnetization or an external magnetic field thereof being oriented in the thickness direction of the magnetic body layer 20; a low-temperature-side conductor part 44 connecting a low-temperature-side end portion 12 of the thermoelectric layer 10 and a low-temperature-side end portion 22 of the magnetic body layer 20; a high-temperature-side conductor part 42 connecting a high-temperature-side end portion 14 of the thermoelectric layer 10 and a high-temperature-side end portion 24 of the magnetic body layer 20; and output terminals (26a, 26b) for extracting a potential generated in the vector product direction of the temperature gradient direction (∇T) of the thermoelectric layer 10 and a magnetization direction (M) of the magnetic body layer 20.
