a Compositions from 1D to 3D for the nacre-mimetic architecture of sensing layer. b Confocal laser scanning microscope (CLSM) images show the surface microstructure for interfacial bridging, and c the stress relaxation curves stretch at 100% strain for PVA, PTF, PTF/MXene, and PTF/MXene/Fe composites, respectively. d Cyclic loading–unloading tensile curves (100 cycles, 500% strain) for PTF/MXene/Fe and PVA composites, the inset showing the cross-section SEM images after 100 stretching cycles. e Finite element simulation of stress distribution within alternating laminated architecture under the vertical uniaxial press of different deformation ratios (9, 14.5, 25.5, 30.6, and 42.5%, respectively).
