SHOCK RECORDING DEVICE

摘要

The present invention provides a shock recording device, comprising: a vibration energy harvester comprising a first electrode and a second electrode, the vibration energy harvester converting an energy of a shock applied thereto into a potential difference between the first electrode and the second electrode; and a ferroelectric transistor comprising a gate electrode, a source electrode, and a drain electrode, the ferroelectric transistor further comprising a stacked structure of a ferroelectric layer and a semiconductor layer. The gate electrode is electrically connected to the first electrode. The source electrode is electrically connected to the second electrode. This shock recording device does not need a power source used to record a shock.
