Future smartphones will feature a temperature-sensitive fingerprint sensor placed under the screen. Finger sensor could be the safer, more efficient solution to authentication problems. In order to protect smartphones from being compromised by fingerprint forgery, they use temperature sensors to distinguish the human print from an artificial print. Additionally, transparent pressure sensors are placed under the display to detect tactile pressures.

The new sensor can be placed beneath the smartphone’s display, eliminating the need for physical buttons associated with fingerprint scanning.

A display-integrated sensor system is beneficial because it optimizes the screen size, allowing for the elimination of a home button. While Apple’s FaceID was a smart solution, it was by no means a perfect one, having issues detecting a face on the first try or detecting faces with certain types of sunglasses, according to

“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.
