The principle of this kind of bio-resistance recognition bracelet is that the flowing currents flow through biological tissues and produce physiological responses, and each individual's reaction is unique because everyone has different bone, meat and blood vessel structures, so we can The difference in biological resistance distinguishes each individual difference.
Human body resistance identification bracelet
At present, the accuracy rate of this body resistance detection technology is only 85%, and there is room for further improvement. This resistance detection technology can only be used in living people, and because the resistance of the human body also has a certain probability of change, so this technology needs further improvement. However, this resistance identification technology undoubtedly lays the foundation for the possibility of rapid identification in the future.
