Abstract
Resonant passive sensors composed by resistive, inductive, and capacitive (RLC) simple sensors are widely used in biotelemetric systems. In this paper, a novel method to read remotely these RLC sensors is presented. The developed method is based on the simultaneous application of three excitation signals of same amplitudes, set at different frequencies, to determine remotely the RLC sensor resonance frequency and quality factor . Theoretical analysis and experimental results are also presented.
