Researchers have developed a stable, wearable bio-sensor to detect diseases such as muscle fatigue, stress and dehydration using trove of medical information which normally present in human sweat.
“When the human body is subjected to strenuous exercise, there is a point at which the aerobic function of the muscles become anaerobic muscle function,” said study co-author Jenny Ulyanova of CFD Research Corporation (CFDRC).
“At this point, lactate produces a faster rate than is consumed. When this happens, knowing that these levels can be an indicator of a potentially problematic conditions such as muscle fatigue, stress and dehydration,” he added.
What distinguishes this study from other studies is the use of pure organic clean technologies. The team, in collaboration with the University of New Mexico have developed a enzyme-based sensor powered by a biofuel cell – providing a secure source of renewable energy.
“Biofuel cell works in this particular case, as the sensor is a device with low power device,” said Ulyanov.
“They are very good at high energy densities, but the power density is still under development. However, for low-power applications, such as this particular transmitter, it works very well,” he added in a report published in the ECS Journal of Solid State Science and Technology .
Despite the fact that the sensor is designed for soldiers in training, it can be applied to people who are active and who engage in strenuous activities.
With regard to commercial applications, the researchers believe that the device can be used as an aid for learning to control lactate changes in the same way that athletes use use heart rate monitors to see how their heart rate changes during training.
