a The strain sensing mechanism of the organogel-based sensor during the stretching and recover process. b ΔR/R0 value of organogel sensor versus the applied strain. c Relative resistance response of organogel senor stored for half a year (25 °C) under different strains. d Relative resistance response of organogel senor at different frequencies under a strain of 60%. e Response and recovery time. f Stability and durability test over successive 2000 cycles (tensile rate 200 mm min−1, 60% strain). g, h Weight changes and conductivity changes of organogel, ionic hydrogel, and PVA/PAA hydrogel after being placed in 25 °C with test time. i Conductivity of organogel in high (45 °C) and low (−60 °C) temperature environment.
