| Abstract Scope |
In this work, we report a printed flexible silver electrode sensor coating with TiO2 nanowires works under room temperature. A silver electrode sensor was printed on polyimide using a VOLTERA commercial printer. TiO2 nanowire was deposited to silver electrodes by an electro-deposition method. The silver electrode sensor works at room temperature without additional heating requirements. The lowest carbon dioxide concentration detection limit for the sensor is 78 ppm. In addition, the response time is around 60s. This indicates the significant progress compared to conventional metal oxides CO2 sensors where a high working temperature (around 250-450°C) is usually required. |
