Description	Journal: Flexible and Printed Electronics Simple fabrication and high environmental stability are eagerly desired for the practical use of temperature sensors in wearable healthcare devices. Herein, we present a fully-printed flexible temperature sensor based on poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) with high humidity stability. Using the novel bilayer passivation, which consisting of a fluorinated polymer (CYTOP) layer and a hydrophilic polyvinyl alcohol (PVA) layer, resulting in a significant improvement in the humidity stability of the PEDOT:PSS-based sensing film. The fabricated sensor exhibited excellent stability under humidity ranging from 30% RH to 80% RH, and high sensitivity of -0.77% ℃-1 for temperature sensing between 25 ℃ and 50 ℃.
