Non-contact Heartbeat Sensor using LC oscillator circuit.
This paper proposes non-contact heartbeat sensor using LC oscillator for personal healthcare. The signals from chest and wrist are measured using LC oscillator and electrodes. The proposed sensor can detect human heartbeat signal without direct contact to skin and is readily a portable heartbeat monitoring sensor. The capacitive and inductive electrodes are addressed, which are key elements of the sensor circuit.
