Abstract
A thermoelectric device includes: a sheet-like or plate-like thermoelectric conversion film including a thermoelectric conversion element formed with a material exhibiting an anomalous Nernst effect; and a catalyst portion formed with a catalyst that reacts with a fluid the catalyst portion being on the side of at least a first surface of the thermoelectric conversion film and facing a flow path of the fluid.
Claims17
A thermoelectric device comprising:
- a sheet-like or plate-like thermoelectric conversion film including a thermoelectric conversion element formed with a material exhibiting an anomalous Nernst effect that generates an electromotive force from heat;
- a high thermal conductive insulating film that is provided on a first surface of the thermoelectric conversion film, and is formed with an insulator having a higher thermal conductivity than the material of the thermoelectric conversion element;
- a catalyst portion formed with a catalyst that promotes a reaction of a gas contained in a fluid to cause a thermal change, the catalyst portion being on the side of at least the first surface of the thermoelectric conversion film and facing a flow path of the fluid;
- a non-catalyst portion that is provided on a surface of the high thermal conductive insulating film and formed with a material not exhibiting a catalytic action for the fluid;
- and
- a readout circuit that is connected to the thermoelectric conversion element and configured to read out a difference between an electromotive force generated in the thermoelectric conversion element due to heat from a region of the catalyst portion and an electromotive force generated in the thermoelectric conversion element due to heat from a region of the non-catalyst portion.
