Even though installing measuring device for safe structure became duty because of structures’ becoming larger, the battery replacement of sensor node is difficult when it is hard to approach such as specific bridges.
This study was done for the examination of the activating possibility wire accelerometer after converting vibration energy occurred from sine wave (±0.2g) to electric energy with cantilevered piezoelectric energy harvester when it vibrates continuously.
