A project by Apple Inc. that involves non-invasive, continuous blood glucose monitoring in the Apple watch is almost complete. The E5 project will be able to measure a person’s body’s glucose levels without the need to prick the skin in the first place.
The report, while citing the people familiar with the matter, added that after hitting major milestones recently, Apple now expects it could eventually bring glucose monitoring to market.
The release of one such innovation will be beneficial for those with diabetes. Apple will also benefit from a stronger position in the healthcare and wearables markets. People usually rely on a tool that pricks the skin to obtain blood.
Currently, there are also skin-indenting patches available from a variety of brands. But they need to be changed every two weeks.
Apple is reportedly using a chip technology known as silicon photonics and a measurement process called optical absorption spectroscopy. The system uses lasers to emit specific wavelengths of light into an area below the skin where there is interstitial fluid (a liquid that flows outside the veins and capillaries) that can be absorbed by glucose.
The light is then reflected back to the sensor in a way that indicates the concentration of glucose. An algorithm then determines the level of a person’s blood glucose. It remains unclear if this algorithm was developed in-house or was outsourced by Apple Inc.
