TECHNOLOGY SUMMARY

In spite of advances made towards the detection of biomarkers in sweat, there is no sensor capable of long-term detection in constricted or load-bearing applications where other flexible plastic sensors might cause discomfort. RooSense developed a flexible fabric sensor made of carbon nanotube-functionalized nylon. The material is further functionalized with a molecule that reacts with sodium ions. As the sensor reacts with sodium ions in sweat, a complex-molecule forms which impedes the flow of an electrical current, allowing the sensor to quantify the amount of sodium present. As sodium ion levels in the sweat increase, athletes must replace these electrolytes to remain hydrated. These dehydration patterns are unique and vary based on diet, weather conditions, and human physiological cycles. Therefore, there is not a “one size fits all” hydration program. The ability to monitor an individual’s hydration parameters is unique to the RooSense sensor and gives it a competitive advantage over “sweat monitors” that monitor water lost or “water timers” that remind the athlete to drink water every 20 minutes. This is the first lightweight fabric sensor to provide real-time information regarding hydration levels during exercise or training through selective determination of sodium ion levels.
