Implant and method of operating the implant
First Claim
1. An implant comprising:
- a receiver that receives first ultrasound signals emitted by a transmitting unit of a further apparatus,wherein said receiver comprises a piezoelement,wherein said piezoelement is excited by the first ultrasound signals at a first series resonance frequency (f1),wherein said piezoelement converts mechanical energy transferred with the first ultrasound signals into electrical energy,wherein said piezoelement is additionally excited at a second series resonance frequency (f2) using the electrical energy, wherein said second series resonance frequency (f2) differs from the first series resonance frequency (f1), and,wherein at the second series resonance frequency (f2), said piezoelement transmits second ultrasound signals.

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.
