Apple working on new blood glucose monitoring device: report

CNBC reported this week that Apple CEO Tim Cook has been testing a new device for monitoring his blood sugar levels. This glucose monitor, a prototype attached to Cook's Apple Watch can track how food consumption and exercise affected the CEO's blood sugar levels.

Back in February, Cook told student at the University of Glasgow that he had been continuously wearing a glucose monitor, but did not confirm if it was an Apple prototype.

 ''It's mentally anguishing to stick yourself many times a day to check your blood sugar,'' Cook 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.''

According to commentators, Apple has been keen on developing what it calls the ''holy grail'' in diabetes management - non-invasive, continuous glucose monitoring. It was reported last month that Apple had a team of biomedical engineers working on the project for five years. If the device worked successfully, the sensors would be able to monitor blood sugar levels without breaking the skin.

According to CNBC, Apple was currently conducting feasibility trials in clinics near Cupertino and was also reportedly in conversations with consultants to figure out ''regulatory pathways.''
