摘要

En 中文

This paper presents an ultra-low power human proximity sensor using electrostatic induction. The analytical model of electrostatic induction current generated by human motion is derived and verified with measurement results. Based on the analytical model, we propose an ultra-low power integrated circuit to detect human motion using electrostatic induction. The test chip implementing the proposed circuit is fabricated in a commercial 250 nm CMOS process. The measurement results of this fabricated chip show that it consumes only 30 nW for detecting human motion, which is less than 1/100(th) of the power dissipated by the conventional human proximity sensors.
