The pulse analytical system realizes the objective classification of pulse and obtains the quantitative target system, by pulse information automatic gathering, analyzing, processing.Pulse sensor is to collects the information of the pulse waveform. The gathering information will effect the following analysis, and it will determine systematic detection performance finally. For a fine performance pulse analytical gathering system, its sensor rational choice plays an essential role. Only because the information that the sensor gathers can reflection fact accurately, the following data processing and analyzing have practical significance.PVDF ( Polyvinylidene Fluoridc ) piezoelectric film is new a kind of macromolecule polymers sensing material, and it has the very strong piezoelectric characteristic.This paper analyzes and discusses the structure of PVDF piezoelectric film and the piezoelectric principle, then designs and produces the single-thread PVDF pulse sensors. Through the static experiment and the signal test of the pulse pulsating, manufacture of the pulse sensors using the PVDF is feasible.
