Flexible Tactile and Shear Force Sensing Array Based on Multilayered Mxene/Carbon Nanotube Composites

摘要

In this work, we present an MXene-based flexible tactile and shear force sensing array using conductive multilayered MXene/carbon nanotube (CNT) composites as the sensing material. The multilayer sensing elements patterned on the nylon membrane substrate have excellent mechanical flexibility and elasticity. The fabricated multilayered MXene/CNT composites have advantages such as high piezoresistive sensitivity, anisotropic sensing capability, flexibility, and simplicity of fabrication. Furthermore, due to the relatively high aspect ratio of the patterned multilayer structure, the proposed sensing element has anisotropic characteristics, which can be employed for better shear sensing. The normal and shear force measurement results using the proposed device are also presented.
