  • Method for contactless electrochemical impedance measurement
    Patent number: 11428657
    Abstract: A sensor for measuring electrochemical impedance includes a primary circuit that includes a primary electrically conducting coil and a secondary circuit that includes a secondary electrically conducting coil. The primary electrically conducting coil is inductively coupled to the secondary circuit. During operation, the secondary electrically conductive couple has contact electrodes that contact a medium for which the impedance is to be measured. An alternating current source energizes the primary electrically conducting coil during impedance measurements.
    Type: Grant
    Filed: June 5, 2017
    Date of Patent: August 30, 2022
    Assignee: University of Southern California
    Inventors: Ellis F. Meng, Lawrence Yu
