IMPACT DETECTING/RECORDING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an impact detecting/recording device capable of detecting and recording an impact applied thereto with no power supply and being miniaturized.

SOLUTION: An impact detecting/recording device 1 includes a ferroelectric memory 3 connected in parallel to an impact sensor 2 which has a piezoelectric element 4 for converting a mechanical energy by the impact into an electric energy and outputting it. The ferroelectric memory 3 has first and second electrodes facing each other via a ferroelectric layer and, is integrated with the impact sensor part other than a part where the piezoelectric element is displaced when the impact is applied to the ferroelectric memory 3.
