Sensors: Bioinspired Optoelectronic Nose with Nanostructured Wavelength-Scalable Hollow-Core Infrared Fibers (Adv. Mater. 10/2011)



Machine olfaction research aspires to mimic the exquisite sense of smell in mammals, using arrays of cross-responsive sensors backed with sophisticated pattern recognition algorithms for the differentiation of thousands of complex odors. on p. 1263, M. Bayindir and co-workers report an infrared-absorption-based odor differentiation in hollow core, wavelength scalable, photonic bandgap fiber arrays. Surprisingly, the specific and cross-responsive nature of the sensor data enable direct binary coding of smell sensations.
