Ammonia (NH3) is an irritant gas with a unique pungent odor; sub-parts per million-level breath ammonia medical biomarker for kidney disorders and Helicobacter pylori bacteria-induced stomach infections. The humidity varies in both ambient environment exhaled breath, thus dependence of gas-sensing characteristics great obstacle real-time applications. Herein, flexible, humidity-independent, room-temperature sensors are fabricated by the thermal evaporation CuBr on polyimide substrate...
Novel zinc oxide quantum dots (ZnO QDs) decorated graphene nanocomposites were fabricated by a facile solution-processed method. ZnO QDs with size ca. 5 nm are nucleated and grown on the surface of template, its distribution density can be easily controlled reaction time precursor concentration.

An electronic nose (e‐nose) mimics the mammalian olfactory system in identifying odors and expands human olfaction boundaries by tracing toxins explosives. However, existing feature‐based odor recognition algorithms rely on domain‐specific expertise, which may limit performance due to information loss during feature extraction process. Inspired olfaction, a smart enabled an all‐feature algorithm (AFOA) is proposed, whereby all features gas sensing cycle of semiconductor sensors, including...
