Disposable and trimmable wireless pressure sensor for medical applications

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;
• 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;
• and
• a laser trimming mechanism for laser trimming said capacitor in order to calibrate data based on said decrease in said resonant frequency and/or for laser trimming said inductor in order to calibrate data based on said increase in said inductance.

A disposable sensor method, comprising the steps of:

• providing a substrate;
• fixing a capacitor and an inductor fixed to said substrate to form a disposable pressure sensor thereof;
• configuring said include an inductor surface, at least one capacitor electrode and a diaphragm, wherein when said diaphragm is exposed to a pressure, said diaphragm moves close to said inductor and/or a surface of 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
• associating interrogation electronics 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.
