Abstract:
1. A thermoelectric generator comprising: a membrane maintained by lateral ends and configured to take a first shape when a temperature of the membrane reaches a first threshold and a second shape when the temperature of the membrane reaches a second threshold greater than the first threshold; at least one electrically conductive element attached to the membrane and connecting the lateral ends of the membrane; and a magnetic element configured to generate, in a region of the membrane, a magnetic field orthogonal to a membrane displacement direction, lateral ends of the conductive element being connected to output terminals of the generator, wherein the membrane is located in the magnetic field during displacement of the membrane between the first and second shapes and wherein a potential difference appears between the lateral ends of the conductive element in response to displacement of the membrane in the magnetic field between the first and second shapes; and wherein the membrane comprises a main metal strip and, at the lateral ends of the membrane, layer portions, superposed to the main metal strip, made of a material having a thermal expansion coefficient lower than that of the main metal strip, the lateral ends bearing against a fixed support.
