Researchers at Washington University in St. Louis are using a locust’s sense of smell to develop new biorobotic sensing devices.

Washington Uni engineers in St. Louis are looking to capitalize on the sense of smell in locusts to create new biorobotic sensing systems that could be used in homeland security applications. A/Prof B. Raman et al are using the sensitive locust olfactory system to develop a bio-hybrid nose. Biological sensing systems are far more complex than their engineered counterparts, including the chemical sensing system responsible for our sense of smell. Although the sense of smell is a primitive sense, it is conserved across many vertebrate and invertebrate species.

For several years and with prior funding from ONR, Raman has been studying how sensory signals are receive...
