Abstract
Systems described herein relate to sensing pressure. In one arrangement, a pressure sensor is disclosed. The pressure sensor includes a circuit including a resistor, an inductor, and a capacitor. The circuit generates an electrical resonance. The resistor is an elastomer having a resistance and connected to an outer surface of an inflatable. The pressure sensor also includes a resonator connected to the circuit. The resonator generates a mechanical resonance coupling with the electrical resonance to create a detuning frequency having a sublinear dependence on the resistance of the elastomer. A pressure of the inflatable correlates with the detuning frequency.
