PROCESSES AND APPARATUS FOR THE INVESTIGATION OF INTERNAL PHYSIOLOGICAL PHENOMENA BASED ON MEASUREMENTS OF THE IMPEDANCE VARIATION OF THE SURFACE OF THE BODY

摘要

A method of investigating physiological phenomena of a portion of a body based upon the variation of the impedance or resistivity of the body. An electromagnetic field is applied to a portion of the body and the field at the surface of the body is then measured. The components of the measured field are used to determine the impedance or resistivity of the the body.
