  • Patent number: 11611236
    Abstract: A self-capacitance based remote power delivery device includes a power source, an energy harvesting device, and a substrate. The power source and the energy harvesting device are configured to be capacitively coupled to a self-capacitive body. The substrate is configured to be capacitively coupled to a portion of the self-capacitive body in contact with the substrate.
    Type: Grant
    Filed: August 6, 2021
    Date of Patent: March 21, 2023
    Assignee: Washington University
    Inventors: Shantanu Chakrabartty, Yarub Alazzawi, Kenji Aono, Erica L. Scheller
  • Patent number: 11464487
    Abstract: A sensor system includes a sensor module that is embedded in a target environment and a signal system. The sensor module includes an active sensor of a first type that detects a target element in the target environment and a reference sensor of the first type that prevents detection of target elements by the reference sensor. The active sensor and the reference sensor receive an ultrasonic signal and respectively generate a first response signal and a second response signal. The first response signal is at least partially as a function of the detected target element. The signal system includes an ultrasonic transducer that generates the ultrasonic signal and receives the first and second response signals, and a controller communicatively coupled to the ultrasonic transducer. The controller identifies the detected target element based at least partially on the first and second response signals.

  • Patent number: 11128168
    Abstract: A self-capacitance based remote power delivery device includes a modulating power source electrically coupled to a grounded substrate, an energy harvesting device coupled to the grounded substrate, and the substrate. The modulating power source is configured to be capacitively coupled to a self-capacitive body. The energy harvesting device configured to be capacitively coupled to the self-capacitive body, and the substrate is configured to be capacitively coupled to a portion of the self-capacitive body in direct contact with the substrate.
