Fig. 4. (a) Schematic representation of the fixed structural coloured wearable and the corresponding resistance change when applying pressure to the PDCLC/AgNW film with a plastic rod. (b) Electrical signal monitoring displayed a reversible resistance change when repetitively applying pressure to the structural coloured e-skin. (c) Demonstration of the multifunctional structural coloured e-skin patched to the index finger. Simultaneous detection of changes to the skin temperature or body motion could be established by the PDCLC/AgNW film. (d) Real-time resistance monitoring of the multifunctional structural coloured e-skin during cyclic finger bending for varying bending angles (θ = 30 or 60°).
