A flexible tactile and shear sensing array fabricated by novel buckypaper patterning technique

In this work, we present a flexible tactile and shear sensing array utilizing patterned buckypaper as the sensing elements. A novel fabrication process for patterning buckypaper with high aspect ratio was proposed. The fabricated sensing device possesses the advantages such as anisotropic sensing capability, flexibility, simple fabrication, and low cost. The measured resistance vs. applied shear force on a single sensing element shows that the element exhibits different sensitivities along different directions. This anisotropic sensing capability can be employed for better shear sensing. The sensing elements also give good sensitivity and repeatability.
