In this paper apply the Current Mode Technology,adopt single chip integration data amplifier AMP 01 which have the specificity of electric current feedback,high-speed,wide band frequency,lower noise and higher precision,to Study Piezoelectric effect and arbitrary dispersed specificity about PVDF film.The equation of Piezoelectric specificity is built.Talk over the integration intelligence structure sensor model of tactility which have the specificity of arbitrary dispersed.Discuss application in bionics skin.
