US EditionNew Noninvasive Device Tracks Hydration Levels Using Bioimpedance
VIRGINIA, UNITED STATES, JUL 14 – The wearable sensor uses bioimpedance to continuously track hydration and alerts users to drink water, potentially aiding health management and preventing dehydration-related risks.
- Scientists at a Texas research institution have created a wearable, non-invasive sensor that continuously monitors hydration levels by measuring bioimpedance.
- The device’s accuracy and practicality were evaluated through multiple tests, such as a study where fluid loss was triggered by diuretic medication and an extended 24-hour monitoring period under normal daily conditions.
- The sensor uses electrical current passed through the arm, where changes in bioimpedance correlate strongly with whole-body water loss and hydration status.
- The study found a strong relationship between variations in arm bioimpedance and decreases in body weight caused by fluid loss, highlighting the sensor's capability for continuous hydration monitoring in real time.
- This technology could improve health management by enabling continuous hydration tracking, aiding athletes, workers, and patients with chronic conditions to avoid dehydration.

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.
