Title:
THERMOELECTRIC CONVERSION ELEMENT, POSITION DETECTION DEVICE USING THE SAME, AND POSITION DETECTION METHOD
Document Type and Number:
Japanese Patent JP2015179746
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve such a problem that, in a positional information detection device using a thermoelectric conversion element, configuration of the device becomes complicated and the manufacturing cost is increased when the number of detection positions is increased.SOLUTION: A thermoelectric conversion element has a plurality of thermoelectric conversion parts which include a magnetic material layer which induces spin current due to the spin Seebeck effect, and an electromotive body layer which is magnetically coupled to the magnetic material layer to generate the current based on the spin current. In the plurality of thermoelectric conversion parts, the potential difference determined by the current based on the spin current and resistance of the electromotive body layer is different from each other.
