CAPACITIVE SENSING FOR PULSE RATE MONITORING

R. Niall Tait

2010

Abstract

This paper describes pulse rate monitoring using capacitive electrodes on finger or wrist. The technique uses a single frequency measurement suitable for low cost and low power applications. The system may enable convenient, comfortable, and continuous monitoring. Pulsatile flow resulted in approximately 5-10 fF of capacitance variation, a level easily measured using inexpensive capacitance measurement integrated circuits.
