Smart contact lens project [Innovation]
posted January 17 2014 10:51.20 by spic0m




Google team is testing a smart contact lens that's built to measure glucose levels in tears using a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material.


"You've probably heard that diabetes is a huge and growing problem-affecting one in every- people on the planet. But you may not be familiar with the daily struggle that many people with diabetes face as they try to keep their blood sugar levels under control. Uncontrolled blood sugar puts people at risk for a range of dangerous complications, some short-term and others longer term, including damage to the eyes, kidneys and heart. A friend of ours told us she worries about her mom, who once passed out from low blood sugar and drove her car off the road.

Many people I've talked to say managing their diabetes is like having a part-time job. Glucose levels change frequently with normal activity like exercising or eating or even sweating. Sudden spikes or precipitous drops are dangerous and not uncommon, requiring round-the-clock monitoring. Although some people wear glucose monitors with a glucose sensor embedded under their skin, all people with diabetes must still prick their finger and test drops of blood throughout the day. It's disruptive, and it's painful. And, as a result, many people with diabetes check their blood glucose less often than they should.

Over the years, many scientists have investigated various body fluids-such as tears-in the hopes of finding an easier way for people to track their glucose levels. But as you can imagine, tears are hard to collect and study. At Google[x], we wondered if miniaturized electronics-think: chips and sensors so small they look like bits of glitter, and an antenna thinner than a human hair-might be a way to crack the mystery of tear glucose and measure it with greater accuracy."
