Abstract: 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.

Abstract: An integrated circuit chip cooling device includes a network of micropipes. A first pipe portion and a second pipe portion of the network are connected by at least one valve. The valve is formed of a bilayer strip. In response to change in temperature, the shape of the bilayer strip changes to move the valve from a substantially closed position to an open position. In one configuration, the change is irreversible. In another configuration, the change is reversible in response to an opposite change in temperature.

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: An electrical generator is composed of a bi-layer membrane enabling the conversion of a thermal energy into electrical energy. The bi-layer membrane is deformable and includes at least two layers having different thermal expansion coefficients. The membrane moves between positions in a reversible fashion in response to heat dissipation and as a function of two flexing temperatures. A magnetic structure associated with the membrane functions to set the flexing temperatures as a function of ambient temperature.
