Figure 2.

Effect of parylene coating on the thermal cyclic characteristics of the mesh thermistor. a) SEM images of composite fibers without parylene coating and with 1 µm parylene coating before and after one‐time heating in an oven at 70 °C for 5 min. b) Changes in the resistance of mesh thermistors with 1 µm parylene coating as a function of temperature. c) Reversible thermal switching behavior of a mesh thermistor with 1 µm parylene coating. Resistances at 25 and 37 °C were extracted from (b) as a function of the cycle number.
