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.

Thermo-electric generator

A method of manufacturing bistable strips having different curvatures, each strip including a plurality of portion of layers of materials, wherein at least one specific layer portion is deposited by a plasma spraying method in conditions different for each of the strips.

Method of manufacturing bistable strips having different curvatures

A power conversion device includes an enclosure containing one or more drops of a liquid. A capacitive electret transducer is coupled to the enclosure. In response to applied heat at a heating surface, the liquid vaporizes and then condenses on a flexible membrane of the capacitive electret transducer. The flexible membrane is displaced in response to the vaporization-condensation and the capacitive electret transducer generates an output current.

Device for converting thermal energy into electrical energy

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.

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.

Thermal energy harvesting device

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.

Event detector

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.

An integrated circuit die includes a substrate having a first layer of semiconductor material, a layer of dielectric material on the first layer of semiconductor material, and a second layer of semiconductor material on the layer of dielectric material. An extended channel region of a transistor is positioned in the second layer of semiconductor material, interacting with a top surface, side surfaces, and potentially portions of a bottom surface of the second layer of semiconductor material. A gate dielectric is positioned on a top surface and on the exposed side surface of the second layer of semiconductor material. A gate electrode is positioned on the top surface and the exposed side surface of the second layer of semiconductor material.
