Abstract: A first closed enclosure defines a cavity having an inner dimension smaller than 5 mm. At least one second resiliently deformable closed enclosure is connected in fluid communication with the first enclosure. A fluid at more than 90% in the liquid state fills the first and second enclosures. A first portion of the first enclosure is in contact with a hot source of a temperature higher than the evaporation temperature of the fluid. A second portion of the first enclosure located between the first portion and the resiliently deformable closed enclosure is in contact with a cold source at a temperature lower than the condensation temperature of the fluid. An electromechanical transducer is coupled to a deformable membrane of the resiliently deformable closed enclosure.

Abstract: A detector of an event includes an electrical energy generator formed by a flexible piezoelectric element with a weight fastened to the flexible piezoelectric element that is biased with the weight in a position with the piezoelectric element flexed. In response to detection of the event, a trigger releases the weight so as to cause a vibration of the piezoelectric element. This vibration is converted by the flexible piezoelectric element into electrical energy. An electronic system is power by the electrical energy and is operable to generate an electrical signal indicative of the detected event.

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: A system for converting thermal energy into electrical power includes a temperature-sensitive element held in a frame by its two ends between a heat source and a cold source producing a thermal gradient. A piezoelectric element is positioned between the frame and at least one end of the temperature-sensitive element. The temperature-sensitive element is configured to deform cyclically between two states under the action of the thermal gradient. With each cyclic deformation, a stress is applied to the piezoelectric element via the one end.
