Abstract: A system and method for providing electromagnetic imaging through electroquasistatic sensing contains an electromagnetic sensor for imaging a sample. The electromagnetic sensor contains drive/sense electronics and a pixelated sensor array having an array of capacitive sensor electrodes that source electric fields that interact with the sample, and wherein the electrodes are individually drivable by the drive/sense electronics in a coordinated manner to establish a desired temporal and spatial pattern in which electrical properties of the electrodes are used to generate an image. Other components of the system include a precision motion controller, sensor head and associated electronics, and a computer for performing data acquisition and signal inversion.

Abstract: A multi-sensor, real-time, in-process current and voltage estimation system is disclosed including sensors, affiliated hardware, and data processing algorithms that allow accurate estimation of currents and voltages from magnetic and electric field measurements, respectively. Aspects of the system may be embodied in a detector that is readily attachable to conductors of an energized system for contactless current and/or voltage sensing of the conductors without requiring the conductors to be disconnected from the energized system.

Abstract: A method and apparatus for making analog and digital electronics which includes a composite including a squishable material doped with conductive particles. A microelectromechanical systems (MEMS) device has a channel made from the composite, where the channel forms a primary conduction path for the device. Upon applied voltage, capacitive actuators squeeze the composite, causing it to become conductive. The squishable device includes a control electrode, and a composite electrically and mechanically connected to two terminal electrodes. By applying a voltage to the control electrode relative to a first terminal electrode, an electric field is developed between the control electrode and the first terminal electrode. This electric field results in an attractive force between the control electrode and the first terminal electrode, which compresses the composite and enables electric control of the electron conduction from the first terminal electrode through the channel to the second terminal electrode.
