a Potential signal versus increasing bending angle, showing two linear segments. The error bars represent the standard deviation, which reflects the dispersion degree of the data. b Potential signal variation under transient bending and recovery conditions. c Potential signal during consecutive upward and downward bending deformation of 60 degree. d Potential signal under repeated bending of increasing angle from 6 to 180 degrees. Inset shows the potential signal at 6 degrees. e Potential signal at different bending frequencies. f Potential signal during 10,000 bending cycles at 40 degrees. Insets show the consistent signal across the whole cycling test.
