Title:
測定ユニットおよび発電装置
Document Type and Number:
Japanese Patent JP7256650
Kind Code:
B2
Abstract:
To provide a measuring unit that is excellent in power generation efficiency and has a simple configuration, and a power generation device of the same.SOLUTION: A measuring unit includes: a case 1; a sensor 2 installed in the case 1; and power generation means 3 such as a piezoelectric element mounted in the case 1. A resonance circuit 4 is provided configured by the power generation means 3 and a coil L1. A range is generated where a frequency band of a natural frequency of a vibrating body 9 vibrating integrally with the power generation means 3 overlaps with a resonance frequency band of the resonance circuit 4. The power generation means 3 may use a speaker or an electromagnetic solenoid instead of the piezoelectric element. In that case, the resonance circuit 4 is configured by providing a capacitor instead of the coil L1.SELECTED DRAWING: Figure 1
