US EditionNew Noninvasive Device Tracks Hydration Levels Using Bioimpedance
THE UNIVERSITY OF TEXAS AT AUSTIN, JUL 14 – The sensor uses bioimpedance to continuously monitor hydration, showing strong correlation with body water loss in tests involving diuretic-induced dehydration and free-living trials.
- Researchers from The University of Texas at Austin unveiled a wearable sensor that continuously measures hydration levels in real time, using bioimpedance technology to provide proactive health monitoring.
- Because dehydration is often overlooked, traditional methods like urine tests are invasive and impractical for continuous monitoring, Professor Nanshu Lu explained.
- She explains the device measures bioimpedance, resistance transmits via Bluetooth Low Energy, and Matija Jankovic said there is a strong correlation with body weight loss.
- Immediate applications include a firefighter using the sensor to prevent dehydration and an office worker being alerted to refill their water bottle, enabling proactive hydration management.
- To broaden applications, the research team said they plan to explore breathable e-tattoos and sweat-soaking wearables, aiming to expand testing and aid in managing health conditions.

A sensor on the upper arm can measure whether someone is losing too much fluid. This provides an extra warning for athletes and firefighters working in the heat.
Wearable Sensor Continuously Measures Body Hydration
A sensor worn on the arm can continuously measure hydration in the body, offering a more precise alternative to other state-of-the-art methods that only offer momentary snapshots and cannot be used to give timely interventions. The non-invasive device described in the journal PNAS assesses bioimpedance in the arm, which correlates with water loss in the body. It allows constant, ambulatory monitoring that can quickly identify dehydration to allo…
A portable sensor measures the liquid balance in real time. The technology is based on bioimpedance and is intended to warn of dehydration early. The post Detect dehydration early – with a portable sensor first appeared on ingenieur.de - job market and news portal for engineers.
