Abstract
A piezo-active device includes a piezo-electric element and an elastically deformable shell in which the piezo-electric element is disposed. The use of this piezo-active device includes, for supplying power to an electrical circuit connected to the piezo-electric element, the step of exerting on the piezo-active device a punctual mechanical action and then allowing the piezo-active device to resonate freely. An appliance includes this kind of piezo-active device, en electrical circuit connected to the piezo-electric element, and means for exerting the punctual mechanical action. A system includes this kind of appliance whose electrical circuit can emit electromagnetic waves and a second appliance adapted to receive waves emitted by the first appliance. Applications include controlling a spotlight.
