Xiaomi unveils large‑scale Sports and Health Lab to advance wearable technology
Xiaomi has officially opened its new Sports and Health Lab, a major research facility designed to push the underlying technology behind next‑generation wearable devices. The lab covers more than 5,000 m² (≈53,800 ft²) and integrates algorithm development, technical pre‑research, and industry‑academic collaboration into one comprehensive platform.
The launch marks a new phase for Xiaomi's wearable R&D, shifting from basic feature development to systematic, deeply integrated research. The goal is to deliver more accurate, reliable, and professional‑grade sports and health tracking for users.
Inside the facility are 23 specialized testing zones that simulate real‑world sports scenarios. These include running, cycling, swimming, strength training, tennis, skiing, bouldering, and golf. There is also a dedicated sports‑fatigue recovery area for studying how wearables can assist during post‑exercise recovery. Xiaomi has additionally built an ecosystem interconnection zone to test multi‑device linkage and cross‑device control features.
To support these scenarios, the lab houses 41 types of professional sports equipment such as oversized treadmills, infinite‑flow swimming pools, ski simulators, and power‑training bikes. It also includes 29 categories of gold‑standard medical‑grade testing instruments, including gas metabolizers, Holter ECG monitors, and VBT speed‑power meters. These tools allow the lab to capture precise physiological data while recreating real sports environments.
The facility is equipped with inertial motion‑capture systems and 62 three‑dimensional optical motion‑capture cameras. Combined with force‑measurement platforms, these systems enable high‑precision recognition of movement posture and biomechanics.
Using these controlled environments and gold‑standard instruments, Xiaomi collects benchmark physiological data and compares it with readings from its wearable devices. This data is fed into Xiaomi's sports and health algorithm models, which are continuously optimized over long periods. As a result, the accuracy of Xiaomi's wearables has significantly improved: calorie‑burn accuracy is up 17%, VO₂ max accuracy is up 15%, sleep‑onset accuracy is up 11%, and deep/light sleep staging accuracy is up 14%.
The lab is also deeply integrated with leading hospitals and universities. Xiaomi collaborates with institutions such as Peking University Third Hospital, Beijing Sport University, Capital Medical University, and Fudan University's Huashan Hospital. Research topics include women's physiological cycle prediction, cardiovascular health, blood‑pressure monitoring, sleep apnea screening, scientific running guidance, and motion‑sickness intervention. The lab also works with global sleep‑medicine associations and has earned certifications from TÜV SÜD and SGS‑CSTC.
Xiaomi states that the Sports and Health Lab will continue to produce cutting‑edge technologies that enhance the performance and accuracy of its wearable devices, ultimately delivering more advanced and intelligent sports‑health experiences for users.
Xiaomi, founded in 2010 and headquartered in Beijing, is one of China's largest consumer electronics and smart‑device manufacturers. The company produces smartphones, wearables, smart‑home products, and IoT platforms used worldwide. Xiaomi has invested heavily in health‑tracking technologies in recent years, aiming to elevate its wearable ecosystem with medical‑grade accuracy and advanced AI‑driven analytics. The new Sports and Health Lab represents a major step in strengthening its long‑term strategy in smart health and fitness.
