  • Radio frequency powered adiabatic stimulation with energy replenishment
    Patent number: 10716948
    Abstract: In one respect, there is provided an apparatus for neural stimulation. The apparatus may include an antenna, a plurality of electrodes, and a voltage supply generator. The antenna may be configured to receive, from an external source, radio frequency energy. The voltage supply generator configured to generate a voltage supply by at least ramping up a voltage of the radio frequency energy in successive increments, wherein the voltage supply drives a current to the plurality of electrodes during neural stimulation. Related methods and computer program products are also disclosed.
    Type: Grant
    Filed: June 15, 2016
    Date of Patent: July 21, 2020
    Assignee: The Regents of the University of California
    Inventors: Sohmyung Ha, Gert Cauwenberghs, Chul Kim, Jiwoong Park, Patrick P. Mercier, Abraham Akinin, Hui Wang, Christoph Hans Maier

  • Integrated electric field sensor
    Patent number: 9360501
    Abstract: An electric field sensor includes one or more sensing electrodes connected to an integrated amplifier that bootstraps all parasitic capacitances at the sensor input to provide for a very high input impedance without the need for neutralization or other adjustments and calibration. The integrated amplifier for the electric field sensor further includes low-noise ESD/biasing structures to stabilize the DC-potential of the sensor with a minimum amount of added noise, leakage and parasitic capacitance.
