Abstract
Addressable elements within chemiresistive microsensor arrays have been operated with rapid temperature modulation in order to improve their ability to detect and monitor species of interest. This approach involves purposeful manipulation of surface adsorbate populations that significantly enhances device selectivity, allowing increasingly complex analyses. In the present work involving three types of oxide sensing films, we focus on systematic methods that have been used to develop materials-specific temperature programs which are tuned for recognition and quantification of multiple trace compounds in test mixtures within air backgrounds.
