Abstract
A system of wireless microtransponders, each including a RF resonator circuit for wireless power induction. An external power coil transmits RF energy at a matching or harmonic frequency to deliver power by near field induction to an intermediate, subcutaneous coil. Power is initially transmitted to a subdermal coil and relayed to the subcutaneous coil. The subcutaneous coil is used to transfer the RF signal and power the microtransponder using the resonator circuit. The external power coil RF frequency is tuned to match or be a harmonic of the micro-coil within the resonator.
Claims22
A wireless transponder system for deep implantation in a patient, comprising:
- a first biocompatible coil;
- an electrical connection coupling said first biocompatible coil to a second biocompatible coil;
- and
- a biocompatible microtransponder wirelessly coupled to said second biocompatible coil;
- wherein said microtransponder is powered by said second biocompatible coil, using power coupled through said electrical connection from said first biocompatible coil.
A deep implantation transponder system, comprising:
- an outer transfer coil implanted proximate to the skin;
- an inner transfer coil implanted proximate to one or more microtransponders implanted at least proximate to biological tissue, said outer transfer coil and said inner transfer coil being electrically coupled together;
- and
- the outer transfer coil tuned to an external power coil for near field magnetic coupling allowing power from the external coil to power said microtransponders.
15-31. (canceled)
A method for powering a deep implantation transponder in a patient, comprising the steps of:
- coupling a subdermal outer transfer coil to an inner transfer coil located proximate to a plurality of microtransponders;
- and
- driving the inner transfer coil at a resonant or harmonic frequency of a resonator power circuit in said microtransponders to power said microtransponders.
