Preliminary study on piezoresistive and piezoelectric properties of a double-layer soft material for tactile sensing
Keywords:Double-layer, Piezoelectric-piezoresistive composite material, Multiwalled carbon nanotubes, PVDF
This paper describes a double-layer simplified sensor unit based on the interesting electromechanical properties of MWNT mixed by polymer composite and PVDF films, which is envisaged to imitate the distributed tactile receptors of human hands so as to help the disabled to recover the basic tactile perception. This paper shows the fabrication and performance research of such a new piezoelectric-piezoresistive composite material which indicates a promising .application in prosthtic hand.
