Electronic Noses Sniff Out Volatile Organic Compounds

Tuesday, May 23, 2023 - 18:23 in Physics & Chemistry

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