Abstract: Recently, relevant researchers said: "A new fingerprint scanning method has been successfully studied, which makes it almost impossible for criminals to escape now." Studies have shown that human sweat pores will produce unique polymers due to sweat discharge, and different reactions will occur when relevant test substances come into contact with these polymers.

With this technology combined with previous fingerprint recognition technology, only a small part of the fingerprint is needed to confirm identity information.
In an article introducing this new technology published in the journal Nature Communications on April 29 this year, researchers stated that sensor technology plays an extremely important role in this new fingerprint analysis and pore clinical diagnosis technology.
In fact, the idea of using sweat pores to confirm fingerprint information has appeared before, but it was abandoned due to time-consuming, poor reliability and high cost. This time, the new technology was invented by a research team led by Jong-Man, a chemical engineer at Hanyang University in South Korea. First, a simple color-changing polymer precipitation is used for inkjet printing. When the fingertip is pressed, the color of the polymer in contact with sweat changes from blue to red, thus forming a unique fingerprint.
Traditional fingerprint identification requires a large area of fingerprint information to be collected, and it is easy to make mistakes during the collection and comparison process. In contrast, this new technology only needs a very small part of the fingerprint to confirm the identity information and ensure accuracy. This new fingerprint identification method can also be used for clinical diagnosis of pilomatricosis.
