Newly developed on-screen fingerprint recognition sensor will detect body temperature | Improve recognition security

The next-generation smartphone fingerprinting module is likely to be embedded in the screen. The new technology needs to be considered for convenience and security. A new article on the famous academic journal Nature Communications was presented on Tuesday, showing Korea. The flexible, transparent fingerprint identification array module developed by the research team can simultaneously detect the pressure and temperature when fingerprint recognition, and ensure the real user to perform fingerprint recognition operation through body temperature detection to improve safety.

The research results are from the Samsung Display of South Korea - a scientist at the UNIS National Science and Technology University (UNIST) R&D Center in South Korea. They explained in the paper that the capacitive fingerprint sensors used in most mobile phones are opaque materials, they need to be fixed by the frame, and Placed under the fingerprint button or under the back button. But the product developed by the team can be embedded in a transparent form, integrating the tactile pressure sensor and the skin temperature sensor function, which can directly realize the screen fingerprint press recognition and meet the FBI safety requirements.
