摘要： A power generation system includes a first power generation apparatus and a second power generation apparatus outputting alternating voltages by an input of vibrations; a first voltage-doubling rectifier circuit not only rectifying the alternating voltages output by the first power generation apparatus to store electricity, but also outputting enhanced voltages to the load instrument; a second rectifier circuit rectifying the alternating voltages output by the second power generation apparatus, and connected in series to the first voltage-doubling rectifier circuit, thereby outputting rectified voltages to the load instrument; a constant-current circuit connected in series to the load instrument, thereby limiting currents flowing to the load instrument to a predetermined current or less.

摘要： A vibration power generation device including a multiple-degree-of-freedom vibration system comprising a first vibration system and a second vibration system, wherein a natural frequency of the first vibration system is different from a natural frequency of the second vibration system. A first mass member of the first vibration system has a hollow structure including a housing space inside, where the second vibration system is housed. A power generating element is mounted on a plate spring of the second vibration system. A support part projects within the housing space, and one end side of the plate spring is attached to the support part and supported within the housing space at a position inward from a peripheral wall of the first mass member. A second mass member of the second vibration system is attached to another end side of the plate spring.

摘要： A transducer in which electrical connections between electrode sheets and leading wires can be secured via an approach other than soldering or welding is provided. In a sheet body portion, a dielectric layer and a first electrode sheet are joined by a first main fusion layer formed of a fusion material. A first conductive portion of a first leading wire is fixed to the sheet body portion by a first clamp. The first clamp includes a plurality of first leg portions that penetrates the sheet body portion in a thickness direction, a first coupling portion that couples the proximal ends of the plurality of first leg portions and is disposed across the first conductive portion, and a plurality of first bent-back portions that is formed by bending the respective distal ends of the plurality of first leg portions and is locked with a second surface of the sheet body portion.

摘要： A power generator including: a vibration system configured to be attached to a vibrating member; and a power generating element attached to the vibration system. The vibration system is a multiple-degree-of-freedom vibration system that includes a first vibration system having a first mass member elastically supported by a first spring member, and a second vibration system having a second mass member elastically connected to the first mass member by a second spring member. The power generating element is arranged between the first and second mass members, and vibration applied from the vibrating member causes relative displacement of the first and second mass members so that vibration energy of the vibrating member is input to the power generating element. A natural frequency of the first vibration system is different from that of the second vibration system.
