Abstract Facile fabrication and high ambient stability are strongly desired for the practical application of temperautre sensor in real-time wearable healthcare. Herein, a fully printed flexible temperature based on cross-linked poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) was developed. By introducing crosslinker (3-glycidyloxypropyl)trimethoxysilane (GOPS) fluorinated polymer passivation (CYTOP), significant enhancements humidity sensitivity PEDOT:PSS film were achieved. The prepared exhibited excellent environmental ranged from 30% RH to 80% RH, −0.77% °C −1 sensing between 25 50 °C. Moreover, wireless platform obtained by integrating hybrid circuit, which performed stable healthcare monitoring.
