This band can collect sweat excreted around the wrists or ankles

Elastic bands with color-changing sensors can provide insights into muscle exertion by measuring sweat acidity on the skin.
This device, developed by John Rogers at Northwestern University, can enhance workplace safety and optimize athletic training.
Rogers suggests, “Monitoring pH levels can prevent muscle soreness and fatigue during workouts, while indicating the effectiveness of exercise.”
For elite athletes, blood lactate levels are crucial indicators of performance, often requiring invasive tests. To address this, Rogers’ team created sweat-monitoring bands with color-changing sensors that can be easily read with a smartphone.
Initial tests revealed that sweat acidity correlates better with blood lactate levels than sweat lactate levels. However, measurements near working muscles showed more accurate results than those taken from wrist bands.
Rogers emphasizes the value of this innovative technology, stating, “Although not exhaustive, it provides novel data previously unavailable.”
His company, Epicore Biosystems, produces disposable patches for sweat and electrolyte monitoring, aiding hydration management in strenuous environments and sports settings.
