This element comprises a support member, a strip-shaped vibration beam, a piezoelectric layer, and electrodes. The first and second ends of the vibration beam are fixed to the support member. The piezoelectric layer and the electrodes are provided on the surface of the vibration beam. The vibration beam extends in a plane when it is not vibrating. The vibration beam has a first portion that extends from the first end fixed to the support member, a second portion that extends from the second end fixed to the support member, and a third portion that connects the end of the first portion opposite to the first end and the end of the second portion opposite to the second end. The vibration beam has a shape such that, when viewed in a direction perpendicular to the plane, a first direction in which the first portion extends is a direction closer to the second end, and a second direction in which the second portion extends is a direction closer to the first end, the first and second directions each make an angle of more than 0° and less than 90° with respect to a straight line connecting the center of the first end and the center of the second end, and the third portion intersects once the straight line.

摘要： An increased frequency power generator that includes a pair of transducers located on opposite sides of a suspended inertial mass. Magnetic attraction is used to couple the mass to each of the two transducers in alternating fashion in response to vibration and other movement externally imparted on the generator. Each transducer includes a suspended magnetic element that couples and decouples to the inertial mass as it reciprocates in the housing due to the applied external moving force. As the inertial mass decouples from one transducer on its way to magnetically connecting to the other transducer, the decoupled suspended magnetic element oscillates at a frequency greater than the imparting force, thereby generating electrical power.

摘要： A microstructure according to embodiments of the present invention comprises a substrate, and a resonant structure having a resonance frequency and comprising a seismic mass and suspension elements for suspending the seismic mass at two opposite sides onto the substrate. The substrate is adapted for functioning as a tuning actuator adapted for applying stress onto the suspension elements, thus changing the stiffness of the suspension elements. This way, the resonance frequency of the microstructure may be adapted to input vibration frequencies which may vary over time or may initially be unknown. By adapting the resonance frequency of the resonant structure, a suitable power may be generated, even in circumstances of variable input frequencies.

摘要： A battery for an electronic device is contained within a first frame that is coupled to a second frame by one or more piezoelectric elements. The second frame is coupled to a device chassis by one or more additional piezoelectric elements. In response to translation and/or rotation of the electronic device, portions of forces induced by the battery mass are transferred to the piezoelectric elements. Electrical energy output by these piezoelectric elements is received in a power controller and can be applied to the battery. Additional device components can also be contained within the first frame so as to increase the total mass that induces forces applied to the piezoelectric elements.

摘要： An object of the present invention is to provide a power generating device which makes it possible to easily generate electric power in a rotating system, such as a wheel including a tire, without impairing the performance and reliability of the rotating system. In the case where the power generating device 10 is mounted to a rotating body such as a tire, the direction of gravity applied to a weight 113 is changed with the rotation of the rotating body to cause beams 111 to be deflected, so that the positions of the deflected beams 111 and the weight 113 are fluctuated in synchronization with the period of the rotation to cause the position of a coil 121 to be displaced. Thereby, the weight 113 is vibrated in the vertical direction in synchronization with the period of the rotation of the rotating body to change the magnetic flux density crossing the coil 121. As a result, AC electromotive forces are generated in the coil 121 to enable electric power to be generated.
