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.

摘要： A piezoelectric resonator including a base part, a first support part fixed to the base part, a beam part fixed to the first support part, a weight part fixed to the beam part, a drive unit provided on the beam part, and an adjusting magnet movable on a main surface of the base part. Furthermore, the weight part is formed of a magnet or a magnetic body, and the beam part extends in a direction along the main surface of the base part. With this configuration, displacement of the resonance frequency generated due to variation in a manufacturing process can be adjusted easily. Even when the resonance frequency is displaced from desired resonance frequency due to variation in the manufacturing process of a power generating element, the displacement can be easily adjusted and maximum efficiency can be obtained.

摘要： A plasmon sensor includes a supporter, a first metal layer on a lower surface of the first supporter, and a second metal layer having an upper surface facing a lower surface of the first metal layer. A hollow space is provided between the first and second metal layers, and is configured to be filled with a test sample containing a medium. The area of the first metal layer is smaller than the area of the upper surface of the supporter. The supporter has a region having hydrophilic property and facing and contacting the hollow space. This the plasmon sensor has a small size and a simple structure.
