Abstract:
Voltage induced on a human body by capacitive coupling to the external environment was measured using a high-impedance measurement head. The body was then earth grounded by means of a Conductive Patch and a Conductive Bed Pad. Each method reduced the coupled 60Hz mains voltage by a factor of at least 70. This result, along with the measurement of the voltage drop across an in-line resistance in the Conductive Patch provided evidence of a simplified electrical network model of the human body.
