When we talk of manufacturers in almost all aspect of technology, surely Samsung is one of the top manufacturer. And one of the aspects in which the company is most active is certainly that of mobile devices. Its innovation comes mainly from the patents it deposits, and in this regard today we talk about one of the latest technological discoveries that could materialize in its next mobile devices.

Everything comes from a patent filed, and published last September 26, by the South Korean giant at the US UPSTO and the WIPO. The document attests that Samsung has technologically designed a smartphone with an integrated infrared spectrometer.

What is Spectrometer?

Generally, a spectrometer is a device that allows evaluating the nature of the constituent material of the objects that it analyzes. For example it could estimate the quantity of sugars in a fruit. Estimate the hydration of the skin or establish the level of oxygen in our blood.

We are not talking of magic here, spectrometer is based on a chemical-physical principle. It emits a light radiation towards an object, which according to its chemical and physical conformation absorbs in a certain way the aforementioned radiation. The object, or rather the material that constitutes it, can reflect or absorb part of the radiation, providing the observer with a sort of easily recognizable “fingerprint”.

According to LetsGoDigital, Samsung planning integrate such a device in a smartphone. The block diagram reported in the patent clarifies that the source of the light radiation would correspond to two LEDs activated by the relative photodiode. Coupled to two detectors capable of detecting the portion of radiation reflected light.

By evaluating, via software, the portion of reflected radiation, it will be possible to estimate the physical and chemical parameters of the object framed. Arriving where possible also to determine its nature.


How Useful Is Spectrometer Sensor On A Smartphone?

One of first question that comes to our mind is “how useful is such a sensor on smartphone?”

Of course, it’s an significant step forward in terms of monitoring physical activity. As well as a valid tool for evaluating the food we are about to eat. However, the accuracy of the instrument will play a fundamental role. It is a spectrometry technique based only on the reflection of the radiation. And, in some cases, could be inadequate. Because it does not consider the refracted portion.

In any case, it would not be a first time for a smartphone. In 2017 the Chinese company Changhong presented a smartphone. With integrated spectrometer at CES in Las Vegas.

Currently, it’s difficult to conclude which of the upcoming Samsung phones will have this sensor integrated to it. The Galaxy S11 that we will probably see at the beginning of 2020. For more information on the patent, we suggest you consult the original document available at this address.
