The clear sensory array will also hide under your display to make the smartphone smarter.
Technology Updates 2018 Which Provide Extra Security to Your Smartphones
Forget fingerprint scanners hidden on the back of your next smartphone or beneath a home button is a new concept in security. The fingerprint sensor under the screen will measures your temperature, just to make sure you are not a robot but a real human.
A group of Korean researchers claimed to have developed a flexible, transparent fingerprint sensor array that can be used to measure pressure and temperature.
The sensor is the work of scientists from the Samsung Display-UNIST Centre at Ulsan National Institute of Science and Technology in South Korea. As they explain in the paper, most capacitive fingerprint sensors currently used in smartphones are opaque, so they need to be hidden away under a bezel, beneath a home button or on the back of the device. While Apple has circumvented this problem with 3D depth-sensing cameras for Face ID, smartphone manufacturers are yet to release a device that hides a fingerprint scanner beneath the display.
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 the resolution shall be as per FBI security standards.
The temperature sensor is designed to detect human skin temperature to make sure you are not using a fake hand or artificial fingerprint to bypass security.
