A recently published patent application by Samsung shows what could be the next step in health monitoring for mobile devices - advanced laser speckle interferometric technology. The document revealed by the US Patent & Trademark Office highlights that, in the future, next to smartwatches and fitness trackers, smartphones and tablets will be able to use this technology as well.

According to the makers of the Galaxy lineup, "A laser beam emitted from the laser light source is scattered on a skin surface of a wrist of a person, and a speckle pattern formed by scattering of coherent light is detected by the detector and then recorded." Devices that use this technology can track heart rate, blood flow velocity and pressure, skin conditions, and more.

This new technology is the result of three patents that Samsung has acquired from Russian developers. The company filed for the patent back in September 2015, and it is unknown when will this technology be used in consumer devices. However, it seems very likely that this will happen sooner or later.

In my early school days, I hated writing and having to make up stories. A decade later, I started to enjoy it. Since then, I published a few offline articles and then I moved to the online space, where I contributed to major websites that are still present online as of 2021 such as Softpedia, Brothersoft, Download3000, but I also wrote for multiple blogs that have disappeared over the years. I've been riding with the Notebookcheck crew since 2013 and I am not planning to leave it anytime soon. In love with good mechanical keyboards, vinyl and tape sound, but also smartphones, streaming services, and digital art.
