Samsung could give future models of the Galaxy Watch a sensor for measuring blood sugar. Such a feature could be a welcome novelty for diabetics, as the prick with the needle for drawing blood could possibly be omitted.
The new health characteristics could look as part of the Galaxy Watch 4 or Galaxy Watch Active 3 in the second half of 2021, according to current rumors from the Far East. As the Korean site ETNews reports, an optical sensor should be able to measure the blood sugar level.
Samsung Galaxy Watch: Optical sensor for blood sugar measurement
Various smartwatch manufacturers rely on optical sensors to measure the oxygen content in order to make the acquisition of the necessary data as easy as possible. As the new report represents, Samsung's blood glucose measurement is to demand on so-called Raman spectroscopy .
In very simplified terms, the light emitted by a laser can be used to determine the blood sugar level without the need for a needle prick, for example. How accurate these measurements are is currently not known. However, it is said that the technology has "the highest predictive accuracy among non-invasive technologies".
In addition to pricking a finger to draw blood, diabetics can now use sensors that are inserted under the skin and continuously transmit their readings to a recipient outside the body.
Other purely optical measurements of current smartwatches, such as the oxygen content, are usually marketed by manufacturers as fitness or wellness functions. The situation is different with the EKG feature, for example in the Apple Watch Series 6, which had received the necessary approval from various health authorities around the world.
Measuring blood sugar in the smartwatch: the next big thing?
Analysts expect that blood glucose monitoring in wearables could be the next big development. So it is not amaze that Samsung is not the only one working on such a technology for its smartwatch. There have been rumors in the past that the Apple Watch will be able to measure blood sugar in the future.
According to the ETNews report, Samsung's new smartwatch will be presented at an unpacked event in the second half of the year. In the most recent Unpacked event on January 14th, Samsung presented the new devices in its S21 lineup and the Galaxy Buds Pro true wireless headphones .
