We’ve heard of many “electronic noses,” but rarely are devices as sensitive as their natural counterparts. adopted.
First of all, yes, grasshoppers actually detect smell via their antennae. I was looking for the possibility of changing to
for new According to the study, a team at Tel Aviv University took one of the grasshopper’s antennas and incorporated it into the electronic system of a wheeled robot.
When that antenna was then exposed to eight different odors (lemon, geranium, marzipan, etc.), electrical signals were generated that were detected and recorded by electronics. A machine-learning algorithm then matched each characteristic pattern in the signal to a known corresponding odor to establish an electrical signature for each of the eight scents. The fun didn’t end there.
“After the experiment was over, we continued to identify additional distinct odors, including different types of Scotch whiskey,” says Dr. Ben Maoz, Prof. Amir Ayali, and Prof. Yossi Yovel, who led the study with a PhD student. said. Neta Shubil. “Compared to standard measurement devices, we have shown that the insect nose sensitivity in our system is about 10,000 times higher than the devices currently in use.”

A paper on this study was recently published in the journal Biosensors and bioelectronics.
So if Airborne Smell tracking is sought after…well, that might be where the Smellicopter comes in. Developed by a team at the University of Washington, it’s a quadcopter drone with a moth antenna that sniffs out the source of the smell.
