In Taiwan, there are almost 96 million people look for medical treatment due to diabetes. The project successfully used the infrared light measurement system to observe the differences between the bilateral feet, and collocating with the Chaos Synchronization to measure the differences between different signals, to decrease the probability of the attendance as the ultimate objective .

The chaotic synchronization system utilizes features such as signal delay and phase. If it is fully synchronized, the equatorial vector difference will converge to zero with increasing time, and the judgment feature will have an error. The PPG signal of the extremities will evolve differently with different degrees of vascular occlusion.

The system is forward-looking in the medical device-related industry, and its approach has the potential to replace clinically standard Rolling Index (ABI) measurements, significantly improving measurement accuracy and efficiency. The system can compete with many sphygmomanometers and ultrasound sensors in the future, and I believe it can replace the current ABI system and become an alternative to rapid screening for diabetic PAD.
