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.
