Abstract
The present invention relates to a stand-alone device for generating electrical energy comprising:—an excitation coil (2) furnished with a central opening, —a magnetic circuit passing through the central opening of the coil and formed of a fixed part (3) and a movable part (5) that can move with respect to the fixed part (3) so as to vary the magnetic flux through the excitation coil (2), characterized in that, —the magnetic circuit passes through the central opening of the excitation coil (2) several times, forming at least one loop. The invention also relates to a remote control device comprising a transmitter coupled to a remote receiver and a stand-alone device (1) for generating electrical energy so as to generate an electric current intended to power its transmitter.
