AB  - Polyvinylidene Fluoride (PVDF) finds a wide range of applications as sensors and actuators properties such as vibration sensors, accelerometer, motion detector etc., due to its outstanding piezo, pyro and Ferro-electric. The present paper signifies the performance of the PVDF sensor as a piezoelectric transducer The objective of this paper is to characterize the PVDF sensors for properties such as linearity, sensitivity, bias stability and response of the material to the shockwave required for transducer applications. A detailed testing and analysis has been carried out to check the suitability of PVDF film for transducer application. The samples were subjected to linearity tests on the shaker for ranges 1g to 18g at a constant frequency of 100Hz and was found to be linear up to 98.06% with respect to acceleration due to gravity (g), and sensitivity was found to be 23mV/g. The samples were subjected to shock of 50g for 11ms and peak to peak output voltage obtained was 20V, Once the shock is withdrawn it takes approximately a microsecond to respond normally. Thus, the PVDF sensor can be used as alternative prime element for the various transducer applications which fulfils the key requirements of wide dynamic range, light weight, desirable size and shape and good sensitivity.
