Abstract (en)
[origin: WO0056210A1] An implant device (32) is provided which is responsive to an external interrogation circuit (38). The implant device (32) includes a structure implantable within a living animal (34) and operatively configured to carry out or assist in carrying out a function within the living animal. The device (32) further includes an electrically passive sensing circuit (not shown) integral with the structure for sensing a parameter associated with the function. In particular, the sensing circuit includes (not shown) an inductive element, wherein the sensing circuit has a frequency dependent variable impedance loading effect on the interrogation circuit (38) in response to an interrogation signal provided by the exciter/interrogator element (36), the impedance loading effect varying in relation to the sensed parameter.
