How High-tech smell sensors aim to sniff out disease, explosives—and even moods

Advances in artificial intelligence, bioengineering and synthetic biology power a new breed of odor sensors, some using living cells 

 

We live in a world of odors—chemical signals that contain valuable data about our health, the environment and even personal choices like which foods, perfumes and beverages we enjoy. Despite decades of research and development, however, this aromatic information has remained mostly untapped. 

 

But now scientists and entrepreneurs are redoubling their efforts to recreate the sense of smell in compact devices that detect and analyze "odors" similar to the way cameras now recognize our faces and microphones our words. In pursuit of these high-tech devices–which could use odors to detect disease like cancer or Covid-19, locate hidden explosives or decipher our moods and behaviors—some companies are leveraging advances in synthetic biology and genetic engineering. Others are harnessing advances in artificial intelligence.
