ABSTRACT: This research proposes the low voltage measurement from a piezoelectric transducer. The vibration source is acquired from water drop impact for different distances. A strip chart was used to record voltage signal from piezoelectric at a 100-Hz sampling rate. The voltage for each sample was saved in excel format and analysed in MATLAB software. The voltage generated has been compared with and analysed for three types of piezoelectric transducers from polyvinylidene fluoride type (PVDF). Based on the experiment and analysis, it was discovered that transducer equipped with ring mass-generated high amplitude voltage compared with other type of PVDF. The finding also showed PVDF equipped with a mass ring oscillated more amplitude voltage compared with PVDF without a mass ring. The voltage comparison between the three types of PVDF at different heights discovers that there are significantly different for each type. The more height increases the more force impact given, which will change the voltage generated by a PVDF transducer. Other than that, the result also showed that the transducer dimension will change the inductive and resistive value and can influence the voltage generated from the transducer.
