Niobium Pentaoxide Thin-Film Gas Sensor for Portable Acetone Sensing

Acetone gas sensing finds application in several fields such as biomedical applications, food industry, chemical manufacturing and environmental monitoring. Often, such applications require good sensing performance and portability of the sensing devices. This paper proposes a conductometric gas sensor based on a thin-film of Nb2O5 able to detect acetone at the sub-ppm level w...
