Selectivity and low power consumption are major challenges in the development of sophisticated gas sensor devices. A sensor system is presented that unifies selective sensor‐gas interactions and energy‐harvesting properties, using defined organic‐inorganic hybrid materials. Simulations of chemical‐binding interactions and the consequent electronic surface modulation give more insight into the complex sensing mechanism of selective gas detection.
