Problem
Traditional fatigue assessment relies on indirect measures such as heart rate or perceived exertion, which do not provide real-time biochemical insight into muscle load. This limits the ability of clinicians, trainers, and workers to detect early signs of overexertion, optimize rehabilitation, or prevent injury during high‑intensity activities.
Solution
Grace Imaging has developed SweatWatch®, a medical‑grade wearable that continuously measures lactate concentration in sweat during exercise. By converting sweat lactate levels into a quantitative fatigue metric, the device offers real‑time, objective data on muscular anaerobic threshold. The sensor data are processed on‑device and can be streamed to cloud‑based analytics for longitudinal tracking and clinical interpretation. Results are delivered through secure dashboards that integrate with electronic health records or training platforms, enabling personalized exercise prescriptions, cardiac rehabilitation monitoring, and occupational fatigue management.
Target Audience
Primary customers are cardiac rehabilitation centers, sports performance teams, and occupational health programs that require objective fatigue monitoring for patients, athletes, or workers engaged in high‑intensity tasks.
