Electromechanical properties of the strain sensors. a I–V curves of the strain sensors with different structures; PEDOT denotes PEDOT:PSS. b Relative resistance variations of the sensors during stretching. c Relative resistance variations of the sensors under a small strain. d Relative changes in the resistances of the sensors based on AgNWs, CuNWs, or carbon nanotubes (CNTs) from 0 to 420% strain. Extraction of the GFs by linearly fitting the plot of the electrical resistance variation as a function of the applied strain. e Comparisons of the average GFs against the maximum stretchability for previously reported strain sensors
