Abstract:
1. A self-powered remote control device comprising: transmission means for transmitting a signal for controlling an electrical apparatus; a power conditioning circuit connected to the transmission means; an electric power generator comprising at least one piezoelectric element for supplying electric power to the power conditioning circuit; control means for controlling the electric power generator, comprising: striking means for generating a calibrated amount of mechanical energy for striking the piezoelectric element with a predetermined second force, thereby mechanically stressing the piezoelectric element to generate electric power; and actuating means actuatable by a first force for actuating said striking means, wherein a magnitude of the second force is not a function of a magnitude of the first force, wherein the piezoelectric element comprises a housing, a flexible metal support and a pad of piezoelectric material located on one face of said support, and the flexible metal support is loosely held within the housing.
