Figure 3. Robust performance of the fibrous temperature sensor. (A) Dependence of temperature and resistance response on external pressing, the pressing force varied from 0 to 10 N. T₀ and T correspond to the temperature measurement before and after pressing, respectively, |ΔT| = |T - T₀|. Error bars are standard deviations of the results from at least three samples; (B) Dependence of temperature and resistance response on bending angle, with the bending angle varying from 0° to 360°. T₀ and T correspond to the temperature measurement before and after bending respectively, |ΔT| = |T - T₀|. Error bars are standard deviations of the results from at least three samples; (C) Dependence of temperature and resistance response on pH, with the pH varying from 0 to 14. T₀ corresponds to the temperature measurement in pH = 7, |ΔT| = |T - T₀|. Error bars are standard deviations of the results from at least three samples; (D) Temperature sensing cyclic tests of the fibrous temperature sensor from 25 to 40 °C.
