Schematic illustration of the preparation of digital-visual fusion CCM e-skin. CNTs, CNFs, and Ti₃C₂ MXene nanosheets were firstly mixed and filtrated to obtain the CCM film. Subsequently, a sticky substrate was fabricated after the precuring of silicone and pigment with the assistance of a PTFE mold. Finally, the CCM film was transferred onto the silicone and pigment substrate and further encapsulated to construct a flexible and user-interactive CCM e-skin, where the CCM layer served as the strain sensing and Joule heating layer, and the silicone and pigment substrate served as the thermochromic component and encapsulation layer. Thus, the CCM e-skin could utilize the digital-visual fusion to realize the intelligent monitoring of human motions
