| Abstract: | Based on the requirement of measurement,PVDF piezoelectric-film was applied to foot-pressure measurement.Taking the 16-point PVDF piezoelectric-film sensor array as example,the working principle of the PVDF piezoelectric-film and the producing process of its sensor array were introduced in detail,and the design of its signal processing circuit was also discussed,and the result of experiment was presented.The experiment indicated that the PVDF piezoelectric-film had better sensitivity,stablization and repeatability,and it could obtain reliable foot-pressure signal.It confirmed that the PVDF piezoelectric-film was suitable to foot-pressure measurement. |
