U.S., April 10 -- ClinicalTrials.gov registry received information related to the study (NCT07520344) titled 'Wearable Photoplethysmography for Non-invasive Hydration Assessment' on April 03.
Brief Summary: Hydration status during exercise is often determined by measuring body mass change, fluid intake and urine output. However, obtaining these measurements can be an invasive, time-consuming process. Hydration status may be detectable by analyzing blood flow patterns of the superficial (just under the skin) blood vessels. Wearable devices are now abundant among the general population, and despite attempts from several groups, a hydration status metric based on noninvasive wearable device metrics has not been developed. With wearables, a li...
