What if you could tell if an apple is poisoned just by pointing your mobile screen at it?
The technology present in smartphones has advanced a lot and not only have revolutionized the way in which millions of people communicate and interact with technology, mobile phones and their innovations make it possible, for example, that a simple sticker turns a phone into a phone. microscope, or that the screen is capable of tell us if a fruit has pesticides.
It is not crazy, it is what the German group Fraunhofer, an organization with dozens of science and research institutes, has developed: a simple application on the smartphone can analyze objects and detect its composition, without external sensors or any accessory.
Analysis of objects with the mobile screen
Instead of opting for spectral analysis in which the different wavelengths on an object are studied to identify patterns and substances, the researchers have used the illumination of the smartphone screen on the object in question to observe it.
Obviously, mobile phones do not include application hyperspectral cameras among their characteristics, so the application calledHawkSpex It combines the screen and the included camera for the analysis of materials: the screen illuminates the object with a series of colors for fractions of a second and the camera checks what it reflects, an information that is combined with the internal calculations and the sample database to obtain the final result.
What use would this have in the real world? Imagine power to know if a lettuce has been treated with chemicals, if the wine that you have been offered is poisoned or if that coffee has caffeine, as well as many other uses in the composition of cosmetic products and food.
Of course, application testing is currently limited to the lab, but those responsible are already working to add real-world samples to the application’s readings for use by first-time users when it hits the market, and it is expected that be later this year.
