Method for anchoring a linear induction generator to living tissue for RFID signal transmission
First Claim
1. A method comprising:
- disposing a moveable ferromagnetic mass in a biocompatible housing,wherein the moveable ferromagnetic mass has a linear axis of operation;
disposing an inductive loop proximate to the ferromagnetic mass;
coupling the inductive loop to a resonator; and
,disposing, using a means of anchoring, the biocompatible housing on a pulsating tissue,wherein the pulsating tissue pulsates in a quasi-sinusoidal rhythm,wherein the linear axis of operation is in an orientation substantially parallel to a normal vector of a surface of the pulsating tissue,wherein the resonator produces an electromagnetic field substantially proportional to the period and the amplitude of the quasi-sinusoidal rhythm of the pulsating tissue.

Abstract
Disclosed herein are systems and methods for an implantable device comprising a ferromagnetic mass at least partially disposed near a coil, said coil formed of electrically conducting material and having electrical leads, a resonator circuit coupled to the leads and operable to resonate on application of energy from said leads. Some embodiments include an antenna coupled to said resonator circuit, wherein when either the ferromagnetic mass or the coil moves, power is supplied to the resonator circuit. In certain embodiments the device further includes a modulator coupled to said resonator circuit and operable to modulate the output of the resonator circuit where either the ferromagnetic mass or the coil is disposed in an animal such as a human. some embodiments allow for disposing multiple devices in an animal for characterizing different animal motions.
