Abstract
Minimal-cost, high-accuracy, and portable devices used to detect the presence of insects at all stages of life, including in the egg stage, in stored products by sensing gas phase markers such as volatile pheromones, semiochemicals, and kairomones. The methods, devices, and systems disclosed herein utilize a sensor array configured to simultaneously measure a plurality of target markers and filter background gases while remaining compact, highly accurate, and easy to operate.
Claims8
A device for detecting one or more target volatile organic compounds (VOCs) within a target fluid flow, the device comprising:
- a sensor array having a plurality of VOC sensors, wherein each VOC sensor includes:
- a substrate;
- a resistive heater circuit formed on a first side of the substrate;
- a sensing circuit formed on a second side of the substrate;
- and
- a chemically-sensitive film formed over the sensing circuit on the second side of the substrate;
- wherein at least one VOC sensor of the plurality of VOC sensors is configured to detect the presence of an insect egg-specific VOC.
