一种仿生神经元纤维皮肤传感器的研究

Study of a Sensor of the Bionics Neurofibril Skin

分析了高分子聚偏二氟乙烯化PZT(PVDF-PZT)薄膜丝纤维束神经末梢在高分子充水薄膜微球层之中呈立式放置和缠绕式放置的三维应力压电效应.通过感应局部深层恒压、斜向深层变化压和表层静压得到触觉、滑觉和温觉.

In this paper, the three dimension stress piezoelectricity (PZT ) effect of the bio-nics neurofibril ends of the polyvinylidene fluoride (PVDF) PZT film is analyzed, Theseneurofibril ends are placed in erection and twining way among the polymolecuar membraneminiballs contained water. By inducing costant pressure in the local deep layer and the sur-face layer and the pressure changing in the tilted direction deep layer with these neurofibrilends, the tactile sensation, the smooth sensation and the thermal sensation can be obtained.
