In an article published in Nature Communications on Tuesday, a group of Korean researchers revealed they have developed a flexible, transparent fingerprint sensor array that can be used to measure pressure and temperature.

According to the research paper, the sensor developed by the team "can be integrated with all transparent forms of tactile pressure sensors and skin temperature sensors, to enable the detection of a finger pressing on the display," and at a resolution that satisfies FBI security standards.

Don't expect the new sensor to detect a fever through your finger just yet -- the temperature sensor is designed to detect human skin temperature to make sure you're not using a fake hand or artificial fingerprint to spoof security.
