Abstract:
Embodiments include an implant and a method of operating the implant. The implant includes a receiver that receives first ultrasound signals emitted by an external transmitting unit of a further apparatus. The receiver includes a piezoelement, which is excited by the first ultrasound signals at a first resonance frequency (f1) and therefrom converts the mechanical energy transferred with the first ultrasound signals into electrical energy. In embodiments of the invention, the piezoelement is additionally excited at a second resonance frequency (f2), which differs from the first resonance frequency (f1), and at the second resonance frequency (f2) operates as a transmitter to transmit second ultrasound signals.

Abstract:
A rectifier circuit rectifies power generation voltage of a piezoelectric element to generate DC voltage and supplies the power generation voltage to a load. Upon termination of a process started upon reception of the DC voltage supplied from the rectifier circuit, the load sets a discharge switch to a conduction state using an output port signal. The electric charge remaining in the piezoelectric element is reset to zero by the discharge switch.
Abstract:
A piezoelectric device is connected in parallel with a diode, and outputs a power generation voltage when depressed. When the power generation voltage exceeds a first threshold voltage, a load switch control circuit makes a load switch be conductive, and when the generated voltage becomes lower than a second threshold voltage, the load switch is cut off. Further, when depression is released, the piezoelectric device is discharged by the diode such that the amount of charge remaining in the piezoelectric device becomes zero.
