NEW YORK-Google said the sensors on the smart contact lens are so small they look like bits of glitter. Google has said it is testing a “smart contact lens” that can help measure glucose levels in tears.
It uses a “tiny” wireless chip and a “miniaturised” glucose sensor embedded between two layers of lens material. The firm said it is also working on integrating tiny LED lights that could light up to indicate that glucose levels have crossed certain thresholds. But it added that “a lot more work” needed to be done to get the technology ready for everyday use.
“It’s still early days for this technology, but we’ve completed multiple clinical research studies which are helping to refine our prototype,” the firm said in a blogpost. “We hope this could someday lead to a new way for people with diabetes to manage their disease.” Many global firms have been looking to expand in the wearable technology sector - seen by many as a key growth area in the coming years. Various estimates have said the sector is expected to grow by between $10bn and $50bn (£6bn and £31bn) in the next five years. Within the sector, many firms have been looking specifically at technology targeted at healthcare.
