The future of fingerprint sensors
The future of fingerprint sensors

The importance of mobile phones and the amount of sensitive information that users contain leads to the constant development of more and better security systems. The pin and the blocking pattern were followed by biometric systems, which started with the fingerprint sensor and in which the facial recognition system now reigns.

But it seems that fingerprint sensors still have to evolve, or at least that is explained by an article published in Nature Communications, where they assure that fingerprint readers will soon be able to measure body temperature and the pressure exerted on them. the same.

Sensors that will know if we are alive

The article talks about a recent study carried out by a team from the Ulsan National Institute of Science and Technology (UNIST), in South Korea. Apparently, in this development scientists from Samsung Display, the component division belonging to Samsung and the main provider of OLED screens in the world, are intervening .

These new sensors that are being developed, would be located under the screen, as in the Vivo NEX, but instead of using optical sensors to illuminate the finger across the screen and perform the reading as we have seen so far, incorporate electrodes based on nanofibers and transparent nanowires, able to detect temperatures between 30 and 45 degrees and also to recognize the level of pressure.

This technology based on fibers, could also allow manufacturers to extend the sensor to a greater part of the screen (or even to all) so that the user can unlock the phone by touching at any point. The development of this new biometrics, seeks to strengthen the security of this type of system that as we have been able to verify, sometimes it is easy to violate.

At the moment we do not know when or how this new system will reach products such as smartphones and tablets, but according to the document, the accuracy of the sensor was sufficient even to meet the FBI standards in fingerprint reading, so it is It is possible that its development comes to fruition.
