Smartwatches have gone beyond fitness tracking and have pretty much ventured into becoming health monitoring devices. A good example of this is the heart rate sensor used in Apple Watch that has opened up the avenue to track multiple health-related issues. But Apple doesn’t seem to be stopping there. According to a new patent spotted by AppleInsider, the company is currently working on a non-invasive glucose monitoring solution that can be used in Apple Watch.
The new patent is titled, “Reference switch architectures for non-contact sensing of substances” and it refers to an electronic device, which can be calibrated to measure the concentration of a substance in a given sample.
It mentions that the new technology uses optical system that can perform absorption spectroscopy, which gets the required data by applying light with known properties, like wavelength and energy, to a sample. The substance in question is said to absorb the energy at certain wavelengths, causing the light’s properties to change upon exiting. The level of this color change will ultimately help determine the concentration of the substance.
While the technology is not said to be perfect for glucose monitoring yet, the report suggests Apple also to be working towards overcoming some limitations such as fluctuations, drifts and variations that could cause accuracy issues.

That said, it could still take Apple a few more years to develop the technology and introduce it in the market. But the patent does give more insight on Apple’s approach to a functioning glucose monitoring system, which was only a rumor till this point.
