Validation of a Wearable Bioimpedance Sensor for Hydration Monitoring
Norway60 participantsStarted 2026-08
Plain-language summary
The purpose of the project is to validate the performance of a wearable bioimpedance sensor (Re:Balans®) for monitoring hydration status. The study includes hospitalized patients aged 65 years or older who are admitted to the hospital with suspected dehydration. Data will be collected continuously throughout the hospital stay using one sensor placed on the back, one on the upper arm, and one on the front of the thigh. Sensor measurements will be compared with multiple reference methods for assessing hydration status, including blood tests, body weight and fluid balance charts. Agreement with these reference measures will form the basis for the performance evaluation.
The anticipated benefit of the project is the validation of a novel, user-friendly, and non-invasive tool for hydration monitoring, with the aim of improving patient care, preventing complications, and reducing the need for hospital readmissions.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
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
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
