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 method for transferring objects onto a substrate, or running substrate, the objects to be transferred being placed in a transfer area containing a carrier liquid forming a conveyor, the objects being held by a compact film of particles floating on the carrier liquid of the transfer area, within which the objects are displaced with the film of particles to be transferred onto the substrate, making at least one connector on at least one of the objects, the connector being made by a substance comprising a polymerizable compound, put in contact with the object arranged within the transfer area, and then by polymerization of the substance.
