A robot that can’smell,’ thanks to a biological sensor
A biological sensor developed by Tel Aviv University allows a robot the ability to smell. The sensor emits electrical signals in response to the presence or absence of an odor. This is what the robot uses to detect and interpret the signal.

Researchers in this study were able, by using a machine-learning algorithm, to detect odors at a 10,000 times greater level of sensitivity than a common electronic device. Researchers believe that this technology could be used to detect explosives, drugs and diseases in the future.

Professors Yossi Yovel, Amir Ayali, and Neta Shvil, a doctoral student at Tel Aviv University’s Sagol School of Neuroscience and Dr. Ben Maoz, of the Fleischman Faculty of Engineering, led the biological and technological breakthrough. The study was published in Biosensors & Bioelectronics.
