Abstract：In this paper the three dimension stress piezoelectricity(PZT) effect of the bionics neurofibril ends of the polyvinylidene fluoride(PVDF) PZT film is analyzed. These neurofibril ends are placed in an erection and twining way among the polymolecuar membrace miniballs contained water. By inducing costant pressure in the local deep layer and the surface layer and the pressure changing in the tilted direction deep layer with these neurofibril ends, the tactile sensation,the smooth sensation and the heat sensation with fuzziness grade can be obtained.
