Abstract:
1. A disposable sensor system, comprising: a substrate; a capacitor and an inductor fixed to said substrate to form a disposable pressure sensor thereof, wherein said inductor comprises an inductor surface, at least one electrode of a capacitor and a diaphragm, wherein when said diaphragm is exposed to a pressure, said diaphragm moves close to said inductor surface and/or said at least one capacitor electrode, thereby resulting in an increase in an inductance and/or a capacitance and a decrease in a resonant frequency associated with said capacitor and said inductor, wherein said increase and said decrease are detectable by external interrogation; and interrogation electronics associated with said inductor and said capacitor, wherein said interrogation electronics externally detect said increase in said inductance and/or said capacitance and said decrease in said resonant frequency.
