Multiband wireless power system
First Claim
1. A module for relaying power wirelessly to a device implanted in a user, the module comprising:
- a structure adapted to be worn by a user;
a receiver configured to receive a first wireless power transmission at a first frequency;
a transmitter configured to transmit a second wireless power transmission at a second frequency different from the first frequency; and
a frequency changer electrically coupled to each of the transmitter and the receiver, the frequency changer configured to convert energy generated by the first wireless power transmission into energy for generating the second wireless power transmission,wherein each of the receiver, the transmitter and the frequency changer are disposed on or in the structure.
