Nitrogen dioxide (NO2) emission has a huge impact on public health and the environment. To detect and control the emission, NO2 sensors are desired. Here, field-effect transistors are investigated as a sensitive and reliable sensor technology. Using the obtained insights in the detection mechanism, a sensor protocol is developed and implemented into a functional NO2 sensor prototype that can detect concentrations as low as 10 ppb of NO2 in real-time.
