Abstract
Odour signals in natural environments are shaped by turbulence, resulting in intermittent, rapidlyfluctuating plumes. These fluctuations carry essential environmental information, but are only accessible to sensorswith sufficiently fast response times. Most conventional sensors are too slow, acting as low-pass filters that obscuremany of the plume’s informative features. Here we present a physics-informed perspective on why fast sensing isnecessary in turbulent environments, and offer a combined approach of fast sensing, plume imaging, and signalprocessing to translate between controlled experiments and real-world deployment.
