摘要： A system configured for producing electric power from sea waves. The system includes a buoyant body; an electric generator including an input shaft adapted to rotate with respect to the buoyant body; a first arm coupled to the electric generator; a second arm; and a pivot joint rotatably joining the second arm to the first arm, said arm. The pivot joint is at a distance, along the first arm, from the input shaft. The first arm connects the second arm to the generator. The tandem arms form a double pendulum system powering an autonomous floating sea analysing station.

摘要： method of fabricating a sensor including a polymer body and a strain gauge including at least one Schottky junction. The Schottky junction includes an active layer including a piezoelectric semiconductor material, preferably with a wurtzite crystalline structure. The Schottky junction further including at least one metal electrode electrically connected to the active layer. The method including the following steps: forming a polymer layer, growing the at least one metal electrode on the polymer layer, then growing the active layer by atomic layer deposition, ALD, on the polymer layer and on the metal electrode. A sensor includes a polymer body and a cantilever including a strain gauge obtained by ALD. A gauge factor of 150 is achieved at different frequencies.

摘要： An electric generator having a rotor with permanent magnets, configured for rotating about a rotation axis; a stator having at least one magnetic yoke with arms extending axially inside or outside of the rotor so as to be adjacent to a radial inner or outer side, respectively, of the rotor; wherein the arms of the at least one magnetic yoke are circumferentially distributed so as to form a slot between each pair of adjacent arms, each slot and each arm showing a width. The widths of the arms and/or the widths of the slots have different values distributed along the circumference. The invention is also directed to a valve having the electric generator equipped with a turbine wheel for being driven by a flow of gas in the valve.
