Artificial enhancements to vision and hearing are nothing new nowadays, but who ever would have thought of noses that can smell better? Finally it seems that the oldest human sense is getting the attention it deserves…in the form of the electronic sniffer.




Wired.com reports that several electronic sniffers, or e-noses, have entered the market in recent years. These mostly cumbersome and expensive contraptions, which are employed by industries ranging from food processing to airport security to health care, sell for anywhere between $10 000 and $50 000.



However, researchers in Argentina have designed a new e-nose that is set to revolutionise the growing market. Wired.com writes that the device is small enough to be portable, yet less expensive than its older, larger rivals. It weighs less than two pounds, can fit into a shoebox and sells for $5 000 to $10 000.
