Abstract: An energy harvesting system for use with the human body may use an eccentrically mounted weight winding a mainspring that drives a mechanical clock mechanism. The mechanical clock mechanism in turn may produce pulses of electricity, for example, through periodic flexing of a piezoelectric or triboelectric material during the regular motion of the mechanical timing mechanism. By remaining in a mechanical rather than electrical domain, improved simplicity and efficiency may be obtained in the generation of regularly spaced uniform pulses.

Abstract: A timepiece includes a mechanical oscillator and an electromechanical transducer formed by an electromagnetic assembly including a coil and a magnet mounted on the balance of the mechanical oscillator. The induced voltage signal, produced by the electromagnetic transducer during each oscillation, exhibits, in a first half-alternation between the oscillator passes via the neutral position thereof, a first lobe of maximum amplitude having a first polarity and, in a second half-alternation following a passage via the neutral position, a second lobe of maximum amplitude having a second polarity opposite the first. An electric converter includes two power supply capacitors and a device for regulating the medium frequency of the mechanical oscillator. The first power supply capacitor is charged merely with a positive voltage whereas the second capacitor is charged merely with a negative voltage. A load pump is arranged to transfer electric loads between the two capacitors according to a time drift of the mechanical oscillator relative to a time base.

Abstract: Provided is an electromechanical transducer to be detachably attached to an electronic device, the transducer including: first and second plates; a rotor rotating around a rotating shaft supported by the plates; a fixed substrate disposed between the plates and facing the rotor; a charged portion having sub-regions disposed on the rotor at intervals in a rotating direction thereof so as to face the fixed substrate; an opposing electrode disposed on the fixed substrate so as to face the rotor; an adjusting unit for adjusting sliding properties of the rotating shaft, the adjusting unit being provided for at least one of the plates; and a gear train coupled to the rotating shaft. The gear train transmits motive power generated by the rotor rotated by electric power of the electronic device to the electronic device or transmits motive power generated by a change in orientation of the electronic device to the rotor.

Abstract: A timepiece and method for mounting a generator in the timepiece, this generator being formed of a rotor with permanent magnets and two coils. A supporting structure is preassembled with the rotor and an electronic module including the two coils is preformed. The method includes the following successive steps for laterally mounting the electronic module in the supporting structure so as to form the generator; assembly of an electronic module support with the supporting structure to form an articulation; rotation of the electronic module thanks to the articulation to bring the two coils closer to the axis of rotation of the rotor, so that these two coils are finally each located in a functional position at the same distance from the axis of rotation of the rotor; fastening of the electronic module to block the articulation after said rotation and thus maintain this electronic module in a functional angular position.
