| Abstract(E) | This study proposes a non-contact human detection method that captures in-vehicle potential fluctuations caused by body motion and breathing using a passive sensor. Although the sensor can be implemented with a simple configuration based on a field-effect transistor, its noise tolerance has been limited. We developed an improved sensor that achieves higher SNR than conventional sensors and supports wired integration with in-vehicle systems. |
