SHOCK RECORDING DEVICE

摘要

The present invention provides a shock recording device consisting of: an electric power source; 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; a first transistor comprising a first gate electrode, a first source electrode, and a first drain electrode, the first transistor further comprising a stacked structure of a ferroelectric layer and a semiconductor layer; and a second transistor comprising a second gate electrode, a second source electrode, and a second drain electrode. The second gate electrode is electrically connected to the first electrode. The second drain electrode is electrically connected to the electric power source. The second source electrode is electrically connected to the first gate electrode. The first source electrode is electrically connected to the second electrode.
