A fast method to estimate body capacitance to ground at mid frequencies

Carles Aliau-Bonet, Ramon Pallas-Areny


Impedance measurements that involve the human body are affected by the capacitance between the body and earth ground. This paper describes a fast method to estimate that capacitance at 10 kHz, which is valid for impedance analyzers intended to measure ungrounded impedances. The method does not require any external component other than two common capacitors and two conductive electrodes in contact with the body.
