Fig. 1: Strain-interference free TES via a biomimetic laminated strategy.

a Conceptional design inspired by the natural nacre. b Schematic overview for preparing sensing layer of TES with TOCNF and MXene building blocks in PVA polymer matrix, as well as spraying Fe(II) among adjacent layers for cross-linking. c The proposed interfacial bridging between Fe(II) and functional groups (-OH, -COOH, and -F), as well as the facile and scalable LBL assembly and compression assisted technique. d Envisioned application of assembled TES for high-fidelity skin temperature monitoring. e Finite element simulation results of structural model demystify the interlayer stress concentration alleviation and in-plane stress diffusion.
