Abstract

Some aspects of the present disclosure relate to a sensor design that exploits the different majority carriers (holes/electrons) in WOand CrOto build sensitivity and selectivity to NO at ppb levels, while discriminating against CO at concentrations a thousand-fold higher (ppm) and spread over a considerable range (0-20 ppm). Practical application of this sensor system for detecting NO in human breath is demonstrated.
