The wearable also has electrocardiogram EKG sensors, which combined with the lactate results, extends the patch s usefulness out of sports tracking, and into medicine.
The two data sets could help- physicians identify, prevent, or manage cardiovascular disease.
Various prototypes have been produced, where scientists worked on finding the correct distance between the sensors to ensure they didn t interfere with each other.
Our bodies produce lactate when muscles require lots of energy very quickly, and is therefore helpful to measure how we re coping when exercising very hard, and is also used when people are being kept alive on life support machines, where it s an important metric for improving chances of recovery.
The team has tested it on three people so far, and has found the EKG is equally as accurate as ones found on fitness bands already.
The Chem-Phys patch is not about to become a product we can buy just yet, but the team says it has already had interest in the device from Olympians, which should help push the product forward.
