A sweat-responsive covalent organic framework film for material-based liveness detection and sweat pore analysis
Q. Hao, X. Ren, et al.
This groundbreaking research by Qing Hao, Xiao-Rui Ren, Yichen Chen, Chao Zhao, Jingyi Xu, Dong Wang, and Hong Liu unveils a revolutionary sweat-responsive covalent organic framework film that not only detects living fingerprints with 100% accuracy but also analyzes sweat pore distribution. With the film's color change from yellow to red upon sweat exposure, it provides a simple yet effective method for liveness detection. Plus, it's reusable after cleaning with ethanol!
