Biological sensor allows robot to detect smells
The robot designed by the Tel Aviv University team is able to detect and interpret electrical signals it receives from the biological sensor, as a response to the presence of a nearby odour. The biological sensor's sensitivity to smell is 10,000 times higher than that of existing electronic devices, the researchers said. “We connected the biological sensor and let it smell different odours while we measured the electrical activity that each odour induced," said Professor Yossi Yovel, one of the researchers on the team. "The system allowed us to detect each odour at the level of the insect’s primary sensory organ. Then, in the second step, we used machine learning to create a ‘library’ of smells." The scientists were able to characterise eight odours in total, including geranium, lemon…
