Abstract
We are conducting research with the goal of realizing an anomaly detection system that operates without the need for batteries by generating electricity from vibration generated by impact and using it as a power source. Since the magnetostrictive type is excellent in durability, it is suitable for power generation using impact. In this study, a guard pipe was used as a structure to attach the device. By measuring the superior frequency of the guard pipe and calculating its vibration mode, we searched for the mounting position of the device. In addition, the device was attached to a guard pipe and shocked to generate power, and the operation of wireless transmission using it as a power source was confirmed. As a result, 0.55 mJ was generated with a single impact, and radio transmission was possible with a single impact on the guard pipe. In the future, we will design a device to use the secondary mode frequency of 378.8 Hz to increase the power generation.
