Abstract
Systems and method to measure pressure are described herein. The system can include a force sensor can that be implanted into a patient to measure, for example, cardiac pressure. The force sensor can include first and second film layers that can define a plurality of pressure cells. An external pressure can deform the pressure cells and change their resonant frequency. When exposed to an acoustic signal, the pressure cells can resonant at a pressure-dependent resonant frequency. The system can detect reflected acoustic waves generated by the resonance of the pressure cells. The system can convert the frequency readings into pressure values.
