The technology is forever changed in the world we live in. Up to now what we find a fingerprint sensor housed on the back and previously the smartphone bears optical fingerprint scanners. Now what you can see is a fingerprint sensor not only read your print but also take your temperature.

According to the article published on Nature Communications explains how future Fingerprint sensor works, a group of researchers in South Korea is working on developing flexible and transparent fingerprint sensors that can measure the pressure applied along with the body temperature of the user through their finger. The scientists working as part of the group belong from Samsung Display-UNIST Center at Ulsan National Institute of Science and Technology.
“In order to prevent the fingerprint forgery using artificial fingerprints, the temperature of human finger skin can be detected using temperature sensors to distinguish real and counterfeit fingerprints…improving security levels further.”
The sensor is “to monitor the temperature range of human finger skin, which enables the recognition of artificial fingerprints, thus improving security.”
This would likely give an add-on feature to the smartphone makers and hardware makers with extra security features to the fingerprint sensor.
“The high resolution of this fingerprint sensor array (318 CPI) sufficiently satisfies the criteria set by the FBI for extracting fingerprint patterns, and its good transparency (89% in the visible light regime) enables its integration into a display,” said the report.
The new sensor may not be able to recognize high fever temperatures, as it is just designed to detect the normal temperature of human skin, but this solution could better protect your smartphone from cybercriminals.
