Abstract
This paper presents the detection of VOCs by functionalised solidly mounted resonators (SMRs) for plant health monitoring. Two designs of SMRs have been developed, one by the University of Warwick (UWAR) and the other by Sorex Sensors Ltd. These were coated with ethyl cellulose and tested for aresponse to linalool – a plant pest biomarker. Both sensors show strong responses, with sensitivities of 1.03 kHz/ppm (UWAR) and 15 kHz/ppm (Sorex). While the Sorex sensor exhibited higher sensitivity, it had a slower response time. In contrast, UWAR SMR responded within 45 sec and showed higher resolution. Results highlight the potential of SMR sensors for rapid and accurate plant health monitoring.
