Mani Teja, et al., “A multi-bit fully integrated thin-film transistor NO2 gas detector at room temperature”, IEEE sensor letters 4 (8), 2020, 5501204. Inexpensive and compact gas sensing systems are indispensable for accurate air quality monitoring with broad spatial coverage. We report an InGaZnO thin-film transistor (TFT)-based integrated NO 2 gas detection system that yields a digital output proportional to the NO 2 concentration. This is the first report on integrated TFT-based detectors where gas concentration is quantified and where simultaneous digital output is provided without
