Giving Computers a Keen Sense of Smell – Researchers Create a Biohybrid Olfactory Sensor

A keen sense of smell is a powerful ability shared by many organisms. However, it has proven difficult to replicate by artificial means. Researchers combined biological and engineered elements to create what is known as a biohybrid component. Their volatile organic compound sensor can effectively detect odors in gaseous form. They hope to refine the concept for use in medical diagnosis and the detection of hazardous materials. Electronic devices such as cameras, microphones, and pressure sensors enable machines to sense and quantify their environments optically, acoustically, and physically. Our sense of smell, however, despite being one of nature’s most primal senses, has proven very difficult to replicate artificially. Evolution has refined this sense over millions of years and researchers are working hard to catch up. A keen sense of smell…
