Grace Imaging is a Japanese medical healthcare startup developing non-invasive wearable technology that measures lactate in sweat to visualize fatigue and exercise intensity. The company is commercializing a sweat lactate monitoring system and associated analysis services for use in sports, wellness, and medical settings, with a particular focus on exercise load measurement and cardiac rehabilitation. Its core technology combines chemistry, electronics, software, and clinical validation to turn sweat-derived biomarker data into actionable insights. Grace Imaging originated from work associated with Keio University School of Medicine and has published clinical and performance studies supporting its approach. The company also collaborates with Mizuno on sweat lactate measurement services such as "RakuTtoRun30" and is pursuing broader healthcare applications for its sensor platform.
