  • Electrodynamic sensors and applications thereof
    Patent number: 8923956
    Abstract: An electrodynamic sensor comprises a high input impedance electrometer adapted to measure small electrical potentials originating from an object under test and having a pair of input probes, characterized in that at least one of said pair of input probes has no direct electrical contact with said object, wherein the circuit arrangement of said electrometer comprises an electrode (1) connected to an amplifier (9), which includes a combination of ancillary circuits cumulatively to increase the sensitivity of said electrometer to said small electrical potentials while not perturbing the electrical field associated therewith.
    Type: Grant
    Filed: February 4, 2011
    Date of Patent: December 30, 2014
    Assignee: The University of Sussex
    Inventors: Terence D. Clark, Robert J. Prance, Christopher J. Harland
