摘要： An energy harvester includes a frame having a base, a first side member affixed to the base, and a second side member affixed to the base and spaced apart from the first side member. A beam is coupled between the first side member of the frame and the second side member of the frame. The beam has a substrate layer with a first end affixed to the first side member of the frame, a second end affixed to the second side member of the frame, a first face, and a second face opposite to the first face. The substrate is elastically deformable in response to the vibratory force. The beam further includes a first piezoelectric layer joined to the first face of the substrate layer and having a terminal for electrical connection to a load, the first piezoelectric layer comprising at least one piezoelectric patch.

摘要： An energy harvester for use to provide power to metrology hardware like gas meters and flow measuring devices. The energy harvester may include an actuator that mounts to a substrate found in the gas meter or in an adjacent, collateral device like a pressure regulator. The substrate may embody a diaphragm or membrane, possibly a thin, flexible or semi-rigid member. The actuator may include piezoelectric transducers that mount to this member. In operation, the piezoelectric transducers can generate an electrical signal in response to mechanical activity (or energy) from the thin member. The electrical signal can be directed to the flow device to replace, supplement, or recharge a power source that powers electronics necessary to expand functions on the flow meter.

摘要： A power supply device (2) is provided with a push-type power generator (4). When a push-button (5) on the push-type power generator (4) is pushed, a variable voltage is generated by a piezoelectric element (6) that excites a primary coil (L1). A high-frequency inverter (8) is activated by the variable voltage, exciting the primary coil (L1), and an alternating field is generated from the primary coil (L1). Secondary power can be supplied by means of the alternating field even if a secondary coil (L2) of an electrical device (10), disposed on a surface of a wall (1) opposite the surface on which the charging device (2) is disposed, is not in contact with the power supply device (2). The secondary coil (L2) of the electrical device (10) causes a light-emitting diode (LED1) to illuminate using secondary power obtained by non-contact power supply.

摘要： Disclosed is an electromechanical generator for converting mechanical vibrational energy into electrical energy, the electromechanical generator comprising: a mass resiliently connected to a body by a biasing device and adapted to oscillate about an equilibrium point relative to the body with an oscillation amplitude, a transducer configured to convert oscillations of the mass about the equilibrium point relative to the body into electrical energy, and a resilient device disposed between the biasing device and one of the mass and the body, wherein the resilient device is configured to be deformed between the biasing device and the one of the mass and the body only when the oscillation amplitude exceeds a predetermined non-zero threshold amplitude. The resilient device may comprise one of a helical spring, an O-ring and a spring washer, such as a Belleville washer, a curved disc spring, a wave washer, and a split washer.

摘要： An autonomous intracorporeal capsule comprises a body containing electronic circuits and an energy harvesting module. The energy harvesting module comprises a moveable surface on the body of the capsule, subjected to pressure variations and to produce a mechanical stress under the effect of the pressure variations, and a transducer comprising a deformable piezoelectric component configured as a beam adapted to be forced to bend. The piezoelectric component has a recessed end integral with the capsule and a free end. A mechanical connection couples the free end of the piezoelectric component to the actuator. The mechanical connection may provide a degree of freedom in rotation between a main direction of the beam and the direction of application of the mechanical stress.
