Abstract: 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.

Abstract: An input device includes a housing, an operation unit, a vibrating body, a piezoelectric element, a picker, and a signal processing unit. The operation unit is movable relative to the housing. The vibrating body has elasticity. The vibrating body includes a first end partially fixed to the housing, and a second end provided so as to be vibratable. The piezoelectric element is provided to the vibrating body. The piezoelectric element is configured to convert vibration energy of the vibrating body into electrical energy as the vibrating body vibrates. The picker flicks the vibrating body to allow the vibrating body to vibrate in conjunction with the operation unit. The signal processing unit is configured to receive power generated by the piezoelectric element to operate and transmit, through wireless communications, detection information to be generated as the operation unit moves.

Abstract: Disclosed herein is a bridge abnormality sensing device including: a pair of vibration sensors installed in an upper structure of a railroad bridge supported with a plurality of bearings, the pair of vibration sensors being provided for two of the bearings arranged in a width direction; a detector circuit configured to output a damage detection signal based on a difference between output signals of the pair of vibration sensors; and an output circuit configured to receive the damage detection signal and notify an external device of any structural damage detected from the railroad bridge. The vibration sensors are vibration power generators that generate power in a frequency range of abnormal vibration resulting from the damage. Power to drive the detector circuit is supplied from the vibration power generators.

Abstract: A power generator including: a first vibration system in which a first mass member is elastically supported by a first spring member; and a second vibration system in which a second mass member is elastically supported by a second spring member, the first and second vibration systems providing a multiple-degree-of-freedom vibration system. A power generating element disposed between the first and second mass members is configured to convert vibration energy input to the first vibration system and the second vibration system from a vibrating member to electrical energy. A resonance frequency of the first vibration system is a frequency lower than 1/√2 times a frequency of a vibration input to the first vibration system from the vibrating member. A loss factor of the first spring member of the first vibration system is at least 0.01 but not greater than 0.2.
