Abstract: The present disclosure relates to a method and a system for driving a first wave emitter and receiver device. The method includes driving the first device throughout channels established via electrical links, wherein at least two of said channels are permuted over time among the electrical links.

Abstract: A method for manufacturing a thermoelectric structure including the following steps: a) providing a substrate made from a first material, b) depositing a thermoelectric element made from a second material on the substrate, by additive manufacturing, preferably by SLS or PBF, c) thinning and cutting the substrate until a film made from the first material is obtained, by means of which a thermoelectric structure comprising a film and the thermoelectric element is obtained.

Abstract: A method for manufacturing a thermoelectric structure including the following steps: a) providing a substrate, covered with a metal layer, b) forming a thermoelectric element on the metal layer, by additive manufacturing, preferably by SLS or PBF, and c) optionally removing the substrate, by means of which a thermoelectric structure, which comprises the metal layer and the thermoelectric element, is obtained.

Abstract: The present disclosure relates to a method for driving a transmitting device, wherein the transmitting device operates with a target frequency (f0). The method comprises: driving the transmitting device by an electrical signal comprising various drive frequencies (f1, f2) selected depending on the target frequency (f0).
