new Wearable Sensor By warning them when their bodies need more water, they can help people avoid the risk of dehydration.
Non-invasive devices developed by researchers at the University of Texas continuously measure hydration levels in real time and transmit data wirelessly On a smartphoneaccording to the SWNS report.
“Dehydration is a quiet threat that affects millions of people every day,” said Nanche Lu, professor at the University of Texas at Austin.

“Our wearable sensors provide a simple and effective way to monitor hydration levels in real time, allowing individuals to take proactive steps. Stay healthy And their best performance,” she added per SWNS.
The sensor uses a method called BioImpedance. Current Through the body through strategically placed electrodes.
The flow of current depends on the hydration of the tissue – hydrated tissue allows current to pass easily, but according to SWNS, dehydrated tissue resists flow.
“ARM’s bioimpedance is not only sensitive to changes in hydration, but is closely aligned with whole body hydration measurements,” says Dr. Matija Jankovic, PhD researcher in Professor Lu’s lab.
“This means that sensors are a reliable proxy for tracking hydration levels, even during daily activities such as walking or working. Or exercise“Yankovic has been added.
The research team conducted the test to verify the device. Multiple experimentsincludes diuretic-induced dehydration studies and 24-hour real-life trials.
Participants received medication to promote fluid loss. Their hydration levels were monitored via wearables and compared to urine samples.

The device showed a strong correlation between changes in arm biocompensation and total water loss, reported SWNS. The findings were published in the minutes of the National Academy of Sciences.
The new sensors can provide an accessible and wearable alternative to traditional hydration tracking methods. Urine or blood analysisit is invasive, time-consuming and unrealistic, researchers noted.
Hydration is known to be essential for regulating body temperature, maintaining organ function and supporting many other important processes.
Even mild dehydration can impair concentration and performance, but severe dehydration can be severe Health issues Experts say, like heat stroke, kidney stones and cardiovascular problems.
Beyond daily use, researchers have said that this technique can be used to prevent chronic dehydration, kidney disease, or Heart condition. Athletes can also use wearables to keep them safe and function optimally, especially in hot weather.
While the current model tracks relative hydration changes, Professor Lu said the team aims to develop reference data for absolute hydration levels.
We are also exploring more advanced wearable formats, such as breathable electronic tattoos and sweat absorbing patches, to enhance comfort during long-term use.

“This is just the beginning,” Professor Lou said, according to a report by SWNS. “Our goal is to have simple hydration monitoring that everyone can access.”
