"a tiny San Francisco startup, Adamant Technologies, is trying to give your iPhone the senses of smell and taste, too.
The company has created a computer chip that works with a bunch of tiny sensors that "can take the sense of smell and taste and digitize them," explains Sam Khamis, Adamant's founder and CEO.
This is not about turning your smartphone into some kind of scratch-and-sniff thing that emits scent. It's about letting your phone or computer or other medical devices smell for themselves.
This was a pretty tricky problem to solve. A computer can easily identify a chemical in the air, but put a bunch of them together and it's stumped. For instance, humans can tell when there's pizza and chocolate chip cookies in the same room. Computers have a harder time with that."
