According to sources, Apple has made significant progress in its watch's no-prick blood glucose tracking technology.
The project, dubbed E5, has been underway for over a decade and aims to measure how much glucose is in a person's body without needing to prick the skin for blood.
- According to sources, Apple has hit significant milestones in the project and believes it could eventually bring the glucose-monitoring device to market.
- Apple is employing a chip technology known as silicon photonics and a measurement process called optical absorption spectroscopy to replicate the results.
- Apple engineers are working to develop a prototype device about the size of an iPhone that can be strapped to a person's bicep.
- An early version of the technology sat atop a table.
- About 1 in 10 Americans have diabetes and typically rely on a device that pricks the skin for a blood sample to test their glucose levels.
