Abstract:

Based on the characteristics of polyvinylidene fluoride (PVDF) piezoelectric materials, a pressure sensor was designed, which consists of probe, charge amplifier circuit, filter circuit and voltage amplifier circuit. The vibrating elastic iron slice was deformed by the contact point displacement. The measurement of pressure can be obtained by measuring the change of piezoelectric signal of the PVDF material on the iron slice. The sensitivity of sensor is 61.22 mV/N and may be applied to various pressure measurement.

Key words: PVDF piezoelectric materials, pressure sensors, pressure measurement
