Flexible fingerprint scanner developed

The key to the lock can be faked, but you cannot reproduce such individual things as the retina or fingerprint. Appropriate scanners are installed on large and small objects - where special reliability requirements are imposed.

Developers from South Korea have created a transparent and flexible scanner. The authors' article, published in Nature Communications, states the following: the system they developed uses an array of flexible electrodes made from ultra-long metal nanofibres and nanowires.

The resolution of the device is 18 dots per inch - enough to distinguish one person from another. After scanning, the information received is verified with the database. If you have access to the territory, the castle opens, and a mark appears in the memory with the date and time of the action.

The scanner is unique in the possibility of its mechanical folding. The device is compatible with pressure and temperature sensors. In this way, it will be possible to distinguish the “live” finger from its exact dummy or a special glove with a papillary pattern. There is simply no way around this protection.

The property of transparency is also in demand in the modern world - because scanners today are actively used in smartphones and other gadgets. If you introduce it into the surface of the screen without depriving the area of ​​other functions (reaction to touch), this will become a real breakthrough. Existing analogues have a lot of disadvantages. The main thing is the lack of sensitivity and a large percentage of errors.
