Room-temperature-operated organic-based acetone gas sensor for breath analysis
Abstract
The sensing performance of sensors based on conducting polymers is greatly affected by the presence of water vapor. The TFB sensor exhibited high sensitivity to acetone, down to ppb levels in ambient air. A humidification tube was designed as an ammonia filter to improve selectivity.
