Abstract

An infrasonic wide band transducer fabricated by polyvinylidenefluoride[PVDF] is studied experimentally. The sensitivity of transducer is fixed -53[dB] at frequency range from $10^{-2}$[Hz] to 2[Hz] and fixed -42[dB] range from 10[Hz] to 400[Hz] respectively. The resonance frequency of the element is 14[Hz], which is accord with the mechanical resonance frequency 25.5 [Hz]. We conjecture that the element is applicable to acoustics, communication system,seismological observation and other similiar fields.
