7. Harbin Institute of Technology: Ultra-flexible transparent graphene wearable sensor for detecting body fluid biomarkers.

Professor Yun Pan Lu of Harbin Institute of Technology published a paper entitled "An Ultra-flexible transparent graphene-based wearable sensor for the detection of biological fluid biomarkers" in ADV MATER TECHNOL, and studied and proposed an ultra-flexible transparent graphene-based field effect transistor (GFET) wearable nano sensor for the detection of body fluid biomarkers. Nanosensors are functionalized by receptors, which can specifically bind to biomarkers, resulting in detectable changes in the carrier concentration of graphene. The sensor consists of 1? M transparent polyethylene terephthalate substrate and WO 3 /Au/WO 3 electrode (transparency is 8 1%) can be installed on eyes for tear detection without affecting vision. These results indicate that the ultra-flexible and transparent GFET wearable nanosensor may be helpful for medical detection applications.

Face recognition

8. New rules for live broadcast: face authentication is required before going online.

Existing netizens found that the live broadcast will be launched soon, ensuring that the broadcaster is consistent with the real-name authenticator, and then it will be gradually opened in various partitions. It is understood that there are some virtual anchors, so some netizens think that this move is some new rules for virtual UP master /vtuber, but it has not been introduced too much.

9. Texas sued Meta face recognition for violating privacy.

On Monday, the Texas attorney general's office sued Facebook's parent company Meta. The lawsuit alleges that Meta's Facebook and Instagram obtained biometric information from photos and videos uploaded by users without consent, and disclosed this information to others, failing to destroy this information within a reasonable time, violating the Texas Privacy Protection Law. People familiar with the matter said that Texas Attorney General Ken? Paxton filed a lawsuit in Marshall District Court, demanding a civil fine of hundreds of billions of dollars for Meta.

1 1, AI referee and coaching system "Guan Jun" appeared in the Winter Olympics.

Xu added another gold to China in the women's freestyle skiing aerial skill final. Behind the brilliant record, a "person" named "Guan Jun" also quickly attracted people's attention. This is because "Guan Jun" is not a human being, but an artificial intelligence referee and coach system developed by Xiao Bing Company. Relying on Xiao Bing's world-leading computer vision and complete frame technology, Guan Jun pioneered the "small sample, big task" ice and snow motion analysis model to provide real-time and professional evaluation and guidance for coaches and athletes.
