Electronic noses sniff out volatile organic compounds

35

Tracing volatile organic compounds is important for public safety and all ‘smell’ related issues. To this end, researchers introduce a fluid mechanics-based chamber design for an electronic nose that consistently detects VOCs at low concentrations. The strategy, which includes using a shunt-like device to control the behavior of fluid flow, is a step forward in e-nose technology development.
