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 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.

Abstract: A light sensor includes a semiconductor substrate supporting a number of pixels. Each pixel includes a photoconversion zone extending in the substrate between a front face and a back face of the substrate. An optical diffraction grating is arranged over the back face of the substrate at a position facing the photoconversion zone of the pixel. For at least two different pixels of the light sensor, the optical diffraction gratings have different pitches. Additionally, the optical grating of each pixel is surrounded by an opaque wall configured to absorb at operating wavelengths of the sensor.

Abstract: The present disclosure relates to a method comprising the following steps: a) forming a waveguide from a first material, the waveguide being configured to guide an optical signal; b) forming a layer made of a second material that is electrically conductive and transparent to a wavelength of the optical signal, steps a) and b) being implemented such that the layer made of the second material is in contact with at least one of the faces of the waveguide, or is separated from the at least one of the faces by a distance of less than half, preferably less than a quarter, of the wavelength of the optical signal. The application further relates to a phase modulator, in particular obtained by such a method.

Abstract: A detection stage of an electronic detection device, for example a pH meter, includes an insulating region that receives an element to be analyzed. The insulating region is positioned on a sensing conductive region. A biasing stage includes an electrically conductive region which is capacitively coupled to the conductive region. The electrically conductive region is formed in an uppermost metallization level along with a further conductive region. That further conductive region is electrically connected to the sensing conductive region by a via passing through an insulating layer which insulates the electrically conductive region from the sensing conductive region.

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.
