  • D.C. epidermal biopotential sensing electrode assembly and apparatus for use therewith
    Patent number: 5560357
    Abstract: The apparatus and method for screening and diagnosing trauma or disease in body tissues involves the use of DC biopotential sensing electrodes having DC offset potentials within an acceptable range and electrical characteristics which enhance the accuracy of the biopotential measurement. The apparatus checks the electrodes connected thereto prior to a measurement cycle and will not initiate the measurement cycle if improper electrodes are present. The electrodes may be formed to selectively pass only certain ions thereby enhancing the sensitivity of the electrodes.
    Type: Grant
    Filed: January 27, 1995
    Date of Patent: October 1, 1996
    Assignee: Biofield Corp.
    Inventors: Mark L. Faupel, Steven Hahn, deceased
