OCPT response of Na+ (a) sensor and K+ (c) sensor under different bending times. Corrosion resistance measurements of Na+ (b) sensors and K+ (d) sensors immersed in artificial sweat. e, g The long-term test stability of the sensors, and the voltage drift values of the Na+ and K+ sensors were 0.15 mV/h and 0.05 mV/h, respectively, after 3 h of continuous testing. f, h the long-term storage stability of the sensors, respectively, and the prepared sensors were stored in a refrigerator with lightproof sealing at 4 °C and tested at weeks 0, 1, 2, 3, respectively (n = 3). The error bars represent the standard deviations of the measured data.
