Abstract: Various embodiments include a mechanical amplification mechanism in a compact power unit of an electricity generator containing at least one piezoelectric element. The power units can be used singly but are also designed to be stacked, serially and/or in parallel with each other, and to be mounted within or under a substrate (e.g., a roadway or aircraft runway) such that the system achieves ultra-high-density of electricity production per unit area. Embodiments of the disclosed subject matter are therefore directed to a mechanical-to-electrical power generator, an accompanying power electronic-circuit, and power transmission and/or power saving into an energy-storage device. Therefore, the generated electrical power can be conditioned for, for example, transmitting to an electrical grid or for charging batteries of electrical vehicles. Other methods of formation of the power units and related systems are disclosed.

Abstract: A controllable brace assembly includes a thigh brace having a thigh gyroscope attached thereto and a shank brace having a shank gyroscope and a shank accelerometer attached thereto. A controllable knee lock couples the thigh brace to the shank brace. The knee lock has an encoder attached thereto. At least one pressure sensor is adapted to be attached to a shoe. A controller is configured to receive signals from the thigh gyroscope, the shank gyroscope, the encoder, the shank accelerometer, and the at least one pressure sensor. The controller transmits a first signal set to engage or disengage the controllable knee lock based on the received signals. A method of controlling the brace is also disclosed.
