We developed battery-less fault diagnostic system using vibration energy harvesting. Compared to the use of batteries, energy harvesting, which generates mW-class power, is limited in the amount of sensor information it can transmit. By applying machine learning algorithms to the analysis, this research has succeeded in achieving highly accurate fault diagnosis even when the amount of data is limited.
