ABSTRACT:
Charging system for implantable hearing aids and tinnitus maskers with a repeatedly rechargeable direct voltage source. The charging system comprises an implantable receiving resonant circuit as the electrical energy source for the direct voltage source to be charged and a transmitting resonant circuit located outside the body that can be inductively coupled with the receiving resonant circuit for power transmission from outside the body to inside the body. Embodiments are provided for transcutaneous and for percutaneous power transmission between the implantable receiving resonant circuit and the external transmitting resonant circuit.
