Sandwiched in this lens are two twinkling glitter-specks loaded with tens of thousands of miniaturized transistors. It's ringed with a hair-thin antenna. Together these remarkable miniature electronics can monitor glucose levels in tears of diabetics and then wirelessly transmit them to a handheld device.
"It doesn't look like much, but it was a crazy amount of work to get everything so very small," he said before the project was unveiled Thursday.
During years of soldering hair-thin wires to miniaturize electronics, Otis burned his fingertips so often that he can no longer feel the tiny chips he made from scratch in Google's Silicon Valley headquarters, a small price to pay for what he says is the smallest wireless glucose sensor ever made.
Just 35 miles away in the beach town of Santa Cruz, high school soccer coach and university senior Michael Vahradian, 21, has his own set of fingertip callouses, his from pricking himself up to 10 times a day for the past 17 years to draw blood for his glucose meter.
