Abstract

See full text

A wearable object (42) including an electronic unit and a power supply unit formed by an electromechanical converter (6A) which includes a rotor (44) carrying first magnets (10A), a mechanical resonator (12A) provided with an inertia mass (46) capable of oscillating at a relatively high resonant frequency and carrying second magnets (20), and coils arranged so that, when the mechanical resonator is oscillating, an induced voltage is generated in these coils. The electromechanical converter is arranged so that the first magnets and the second magnets can, during a rotational drive of the rotor, interact magnetically so as to apply to the inertia mass, momentarily or temporarily, a magnetic force torque allowing to excite the mechanical resonator, in order to generate at least one oscillation of this mechanical resonator at its resonant frequency in order to generate a relatively high induced voltage allowing to recharge an accumulator.
