| Summary: | This work reports on printed organic PEDOT:PSS sensors for the detection of hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) vapors. Compared to commercial devices, the proposed sensors are thin and flexible, allowing their simple integration into an industrial process for multilocation decontamination monitoring. The sensors show a reproducible behavior in a laboratory environment using chambers containing a concentration of 130 ppm of H<sub>2</sub>O<sub>2</sub>, measuring an increase in resistance of ~1200% for 1 h exposure. The results highlight the importance of contact interfaces and their encapsulation for reproducible sensing behavior. These devices are promising as low-cost disposable devices for decontamination process monitoring. |
