Apple is testing a non-invasive glucose monitor to potentially include in next Watch

Apple’s chief executive Tim Cook has been spotted at the Apple campus test-driving a device that tracks blood sugar, which was connected to his Apple Watch. Cook was wearing a prototype glucose-tracker on the Apple Watch, which points to future applications that would make the device a “must have” for millions of people with diabetes — or at risk for the disease.

The company has a team working on the “holy grail” for diabetes, CNBC reports. Non-invasive and continuous glucose monitoring. The current glucose trackers on the market rely on tiny sensors penetrating the skin. Sources said the company is already conducting feasibility trials in the Bay Area. Cook also reportedly talked about the device last February to students at Glasgow University, where he received an honorary degree. “I’ve been wearing a continuous glucose monitor for a few weeks,” he said. “I just took it off before coming on this trip.”

At the ‘fireside chat‘ Cook explained that he was able to understand how his blood sugar responded to foods he was eating. He made modifications to keep his blood sugar more constant. He reiterated Apple’s commitment to the health space and spoke about the struggles faced by people with diabetes. “It’s mentally anguishing to stick yourself many times a day to check your blood sugar,” he said. “There is lots of hope out there that if someone has constant knowledge of what they’re eating, they can instantly know what causes the response… and that they can adjust well before they become diabetic.”

Cook also described the impediments in the US to making high-quality and intuitive health products, namely the priority for medical device makers to get reimbursement from insurance companies. “This is an area where I’m very excited about Apple’s contribution,” he said. “Very excited.”
