Fig. 3

a Schematic illustration of the structure of the LM strain sensor. b Optical images of the sensor under different deformation modes: (i) initial state, (ii) twisted, (iii) rolled, and (iv) stretched. c Relative change of electrical resistance versus strain of the LM sensors with different SiO2 filler loadings. d Mechanical simulation results of strain distributions within the LM sensors based on pure LM (top) and LM-SiO2 composite (bottom) under 100% tensile strain. e Reversible loading-unloading behavior of the LM sensors with different SiO2 filler loadings. f Relative resistance change during cyclic stretching-releasing test.
