The characteristics of the PVDF piezoelectric-film were studied.Based on the feature of the foot,a PVDF piezoelectric-film sensor which is insole-like,multi-point measurement and is proper to measure shoes'foot-pressure was designed.A portable foot-pressure measurement system which has a foot-pressure distribution measurement,a ZigBee wireless data communication,and a measurement data analysis and administration function was proposed.It is shown that the system has the features of a stable performance,easy-...
