With roots in North Carolina State University, Onda Vision Technologies (OVT) is housed in the Universitys Advanced Self-Powered Systems Integrated Sensors and Technologies (ASSIST) Center - an NSF sponsored Nanosystems Engineering Research Center (NERC). It is well-known that acute and chronic changes in hydration state caused by external (heat) or internal (disease) stress on the human body leads to adverse health conditions. Onda Vision is structured around looking beyond what is visible to monitor changes in a hydration state. Principals of the firm are addressing development of a proactive-based approach to predict onset of exertional heat illness - a consequence of when the human body fails to maintain core temperature within a narrow range (33.2?-38.2?). The firm is addressing development of a novel, low-cost wearable hydration sensor, coupled with predictive analytics, to monitor and report changes in an athletes hydration state. If effective, the system could mitigate athlete injuries, reduce medical costs, and minimize the risk of long-term adverse health conditions
