Abstract
Disposable pressure sensor methods and systems are disclosed. A substrate can be provided, along with a capacitor and an inductor fixed to the substrate to form a pressure sensor thereof. In a variable L configuration, the inductor can be configured to comprise an inductor surface and a diaphragm, such that when the diaphragm is exposed to a pressure, the diaphragm moves close to the inductor surface, thereby resulting in an increase in the inductance and a decrease in the resonant frequency associated with the capacitor and the inductor and any associated circuitry. In a variable C configuration, the capacitor can be configured to comprise one electrode on the surface and one on the diaphragm, such that when the diaphragm is exposed to a pressure, the diaphragm moves close to the capacitor surface, thereby resulting in an increase in the capacitance and a decrease in the resonant frequency associated with the capacitor and the inductor and any associated circuitry. Such increase and/or decrease data are detectable by external interrogation.
