Scientists at Israel's Tel Aviv University (TAU) have created a biological sensor to help robots detect and interpret odors.

TAU's Yossi Yovel said the researchers mated the sensor to an electronic system and had it smell different odors while measuring electrical activity induced by each scent.

Said Yovel, "The system allowed us to detect each odor at the level of [an] insect's primary sensory organ. Then, in the second step, we used machine learning to create a 'library' of smells."

The algorithm can identify smells with 10,000 times greater sensitivity than a standard electronic device.
