Abstract :
This paper presents a study of a wireless battery-less passive telemetric system aimed at environmental sensing. The system uses a capacitive sensor configured as an LC-oscillator which resonant frequency shifts with the physical measurement. The expected performance of this system including sensitivity is analyzed with respect for coupling factor and sensor/circuit parameters
