Researchers from the Tokyo University of Science have developed a unique sweat sensor that can continuously monitor lactate levels to predict muscle fatigue.
The sensor overcomes the common issue of air bubbles interrupting measurements by incorporating a larger sweat reservoir that traps the bubbles. The study, published in ACS Sensors, confirmed the effectiveness of the sensor's bubble-trapping mechanism and demonstrated stable lactate measurements for two hours.
The researchers believe this invention can contribute to health monitoring and athlete training management, offering a non-irritating and flexible solution for continuous lactate level monitoring in sweat.
In connected developments, Gatorade introduced a sweat-tracking patch and fitness monitoring app for athletes to monitor hydration and other metrics whilst Tufts University researchers have developed a sensor patch that can be sewn onto clothing to track sweat biomarkers
