Observation of human impedance at 50 kHz for analysis of acupuncture points

Abstract

Human skin impedance was measured at 50 kHz. The measurements were performed on putative acupuncture points and surrounding sites of the pericardium and lung meridian located on the skin between the metacarpophalangeal joints and elbow of a healthy volunteer. Results showed acupuncture point could be identified by skin impedance measured with a 2 mm diameter searching electrode.
