Our key technologies are divided into two types: one is optical calculation, where we project light onto an object with a special pattern to get contour lines; the other is smart stickers: smart stickers are a kind of post-installed environment or wearable sensors. Upload the sensed temperature, displacement, pressure, blood pressure, pulse, ECG, EEG, and sweating to the Internet of Things through Bluetooth. Smart stickers are ultra-thin, shock-resistant, water-repellent, high-temperature resistant, soft and flexible, and can be easily and closely adhered to various uneven surfaces, such as human bodies, urine bags, medical equipment surfaces or industrial products. After measuring the overall frequency of the object to be measured with an optical computing photoelectric measuring device, the smart patch can be attached, and the smart patch can be attached to the correct position, and the overall behavior response of the belt can be understood. The smart stickers launched by the team include hardware (smart stickers with different functions), big data management (cloud management), and artificial intelligence event prediction, such as: early warning of equipment needs maintenance, patient life index decline and other events. Because of the automatic wireless Internet transmission function and 24-hour automatic detection function, it is very popular to analyze machine parameters or human physiological conditions. We currently have signed industry-academic cooperation projects ("smart LED laser, patch circuit board to improve video cameras", "car tracks, bridges, building disaster prevention optical monitoring systems" and "light healing wearable devices"). These plans cooperate with our unique AI 5G big data Internet of Things, which can greatly improve its technological standards, and are widely used in Industry 4.0 and precision medicine.
