Abstract: A thermo-electric generator includes a semiconductor membrane with a phononic structure containing at least one P-N junction. The membrane is suspended between a first support designed to be coupled to a cold thermal source and a second support designed to be coupled to a hot thermal source. The structure for suspending the membrane has an architecture allowing the heat flux to be redistributed within the plane of the membrane.

Abstract: A system includes a hot source, a cold source, and a device thermally coupled between the hot source and the cold source. The device includes a thermal-mechanical transducer and a mechanical-electrical transducer. The thermal-mechanical transducer includes a band of bimetallic strips linked mechanically together by their longitudinal ends. The band partially suspended over a portion of a substrate. Each bimetallic strip has a first stable state having a first curvature and a second stable state having a second curvature opposite the first curvature, and adjacent bimetallic strips have opposite curvature.

Abstract: An electrical generator is composed of a bi-layer membrane enabling the conversion of a thermal energy into electrical energy. The bi-layer membrane is deformable and includes at least two layers having different thermal expansion coefficients. The membrane moves between positions in a reversible fashion in response to heat dissipation and as a function of two flexing temperatures. A magnetic structure associated with the membrane functions to set the flexing temperatures as a function of ambient temperature.

Abstract: An integrated circuit chip cooling device includes a network of micropipes. A first pipe portion and a second pipe portion of the network are connected by at least one valve. The valve is formed of a bilayer strip. In response to change in temperature, the shape of the bilayer strip changes to move the valve from a substantially closed position to an open position. In one configuration, the change is irreversible. In another configuration, the change is reversible in response to an opposite change in temperature.
