Digital photonic nose for machine olfaction

Researchers at UNAM developed an infrared absorption based photonic nose that uses photonic bandgap fibers to differentiate and assign unique binary codes to odorous molecules, opening a new path for photonic based olfactory sensors. 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. Each odorant, with …
