New wearable sensor could spot dehydration in seniors
NCT ID NCT07655401
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a wearable sensor that measures hydration levels in older adults (65+) admitted to the hospital with suspected dehydration. The sensor is placed on the back, arm, and thigh, and its readings are compared with standard methods like blood tests and weight changes. The goal is to see if this easy-to-use, non-invasive tool can help doctors better manage hydration, prevent complications, and reduce hospital readmissions.

Inclusion Criteria: * Age ≥ 65 years * Planned fluid management due to presumed dehydration * Expected duration of hospital stay ≥ 3 days Exclusion Criteria: * Known allergies or skin sensitivities to electrode hydrogel and/or acrylic adhesives * Implantable pulse generators such as pacemakers and defibrillators, and/or use of other electrical medical equipment for which an interaction effect with the investigational device cannot be ruled out. * Scheduled MRI * Scheduled diathermy * Breached skin at device application areas (upper back, anterior thigh and upper arm) * Unconsciousness * Critically ill (presence of acute organ dysfunction requiring intensive monitoring and management) * Any medical or psychiatric condition, which in the opinion of the investigator precludes participation * Incapable of giving informed consent
