Abstract :
In this paper a new system for the remote interrogation of wireless battery-less passive sensors aimed at environmental sensing is presented. The system uses a capacitive sensor configured as an LC-tank which resonant frequency shifts with the physical measurement. The overall performance of the architecture is analyzed with respect to coupling factor and sensor parameters.
