Thin film electronic devices are being developed for gas sensors, based on organic transistors platform.
Devices currently under development for detection of volatiles relevant to the agricultural industry
These sensors offer opportunity for information-led intervention in current practices:
Monitor quality during storage and transport
Early detection of adverse events: disease, rot, infestation
Potential to be tailored and designed to sense multiple gases at the same time
Potential to discriminate between complex mixtures of gases based on “fingerprinting” of the output responses (e-nose approach)
Lower power consumption compared to metal oxide sensors that in turn allows for potential long-term standalone operation and creation of wireless sensor networks for remote monitoring
Can be fabricated using mainstream solution-based coating technologies
Through a research project part-funded by Innovate UK, CDT has collaborated with The University of Manchester, The University of Greenwich and The National Institute of Agricultural Botany – East Malling Research (NIAB EMR) to develop gas sensor systems for the early detection of rot in apple crops.
