  • Patent number: 10712879
    Abstract: Aspects disclosed in the detailed description include a touch capacitance transduced energy harvesting system. The energy harvesting system includes a touch sensing electrode array and energy harvesting circuitry coupled to the touch sensing electrode array. When a movable conductive object (e.g., a human finger) moves toward or away from the touch sensing electrode array, capacitance of the touch sensing electrode array increases and decreases accordingly, thus transducing a direct current (DC) current in the touch sensing electrode array. As such, the energy harvesting circuitry can be configured to harvest electric energy from the DC current to generate and store a DC voltage. By harvesting the electric energy transduced from the kinetic energy of the movable conductive object, it is possible to power a low-power electronic device (e.g., a biosensor) with motions already used for interfacing with the low-power electronic device.

  • Patent number: 10312830
    Abstract: Electrostatic generator electrodes mounted on the outer surface of a fiber-composite rotor. The conducting strips are mounted with a slight tilt in angle such that the electrodes will experience no tension or compression effects as the rotor spins up or slows down. The compression would come about from effects associated with the Poisson Ratio. This change can eliminate any metal fatigue or loss of bonding that might have arisen if the electrodes were to be aligned with the axis.

  • Patent number: 10298090
    Abstract: A geometric design of E-S generator/motor electrodes mounted on the inner surface of a fiber-composite rotor is provided. The electrode configuration is able to sustain very high g levels. The rotor may be formed of carbon-fiber wound on top of an inner E or S-glass fiber composite core. The electrode design provides the needed area to satisfy the power requirements of the storage system and utilizes a stacked wedge-like electrode array that both solves the high-g problem and results in a doubling or tripling of the electrode area, relative to that of electrodes that conform to the inner cylindrical surface of the rotor.

  • Patent number: 10259702
    Abstract: Caging structures are disclosed for caging or otherwise reducing the mechanical shock pulse experienced by MEMS device beam structures during events that may cause mechanical shock to the MEMS device. The caging structures at least partially surround the beam such that they limit the motion of the beam in a direction perpendicular to the beam's longitudinal axis, thereby reducing stress on the beam during a mechanical shock event. The caging structures may be used in combination with mechanical shock-resistant beams.
