  • Torsional moving electric field sensor with modulated sensitivity and without reference ground
    Patent number: 11061059
    Abstract: The present invention relates in general to a novel microelectromechanical sensor device for detecting and measuring electric field and magnetic field. In particular, the sensor device of the present invention is useful for measuring low and high strength electric fields and magnetic fields without reference ground connection, the device comprising a first electrode and a second electrode rigidly connected together via a joining segment so that the first electrode and second electrode are mutually and dependently pivotal about an axis passing through a joining segment to form a tiltable unit, and the first electrode and the second electrode are electrically isolated from each other. The present invention further provides novel methods of using through specific arrangement of such novel sensor device.
