Jong-Heun Lee and co-workers have developed a general and easy solution to mitigate the water poisoning effect in oxide semiconductor gas sensors by coating them with a moisture-blocking Tb4O7 overlayer. This method preserves the gas-sensing characteristics, such as gas response, selectivity, and sensor resistance, enabling the creation of reliable gas sensors and artificial olfaction systems with strong endurance against variations in ambient moisture.-Scientific Journal cover design by scapiens
