Apple recently filed a patent application with the United States Patent and Trademark Office (USPTO) entitled “Using environmental sensors to enhance terahertz spectroscopy and imaging performance in a dynamic environment”, pointing out that the device can use absorption spectra Come to get blood glucose readings non-invasively.
The patent mentions that this technology can use terahertz electromagnetic radiation instead of light to pass through the body to detect the “quality of gas, health or liquid-solid materials”, and can also be used to detect skin cancer and other related problems.
The patent also mentions a potential problem, as this technology requires openings, which may cause the device to lose water resistance. At the same time, this technology may mean faster battery consumption than before and may cause equipment prices to rise.

It is not clear whether Apple will bring non-invasive blood glucose monitors to the Apple Watch, but it at least means that Apple is considering developing this product.
It is worth mentioning that Samsung will be equipped with a blood glucose monitor in the next smartwatch to be launched later next year.
