In article number 2007895, Jong‐Heun Lee and co‐workers show that the coating of a moisture‐blocking Tb 4 O 7 overlayer provides a general and facile solution to mitigate the water poisoning effect of oxide semiconductor gas sensors without significant alteration of the gas‐sensing characteristics such as gas response, selectivity, and sensor resistance, enabling the design of reliable gas sensors and artificial olfaction with the strong endurance against the variation in the ambient moisture.
