Aiming at deficiencies of infrasonic wave sensor for infrasonic detection

at present

design a kind of vibration wire infrasonic wave sensor based on PVDF

establish mathematical model for vibration wire

elastic element and piezoelectric thin film

design conditioning circuit

test and verify the sensor. The results show that the sensor has the advantages of a full range of receiving infrasonic wave

adjustable range

high sensitivity

small error and so on.
