A new wearable sensor can help people avoid the dangers of dehydration, when their body needs more water.
According to SWNS reports, the non-invasive device, developed by researchers at the University of Texas, constantly measures the level of hydration in real time and wirelessly transmits data into smartphones.
“Dehydration is a silent threat that affects millions of people every day,” said Professor Nasshu Lu at the University of Texas in Austin who led the study.

He said, “Our wearable sensor provides a simple, effective way to monitor the level of hydration in real time, empowers individuals to stay healthy and take active steps for their best performance,” he said, according to SwNS, per Swms.
The sensor uses a method called bioempration, which sends a small, safe electric current through the body through the strategically placed electrode.

The current of the current depends on how the tissues are hydrated – the hydrated tissue allows the current to pass easily, while the dehydrated tissue opposes the flow according to SWNS.
“ARM bioemption is not only sensitive to hydration changes, but also closely align with the hydration measurement of the entire body,” the study co-writer Dr. Matija Jankovich said, a post-doctoral researcher in Professor Lu’s lab.
“Dehydration is a silent danger that affects millions of people every day.”
“This means that the sensor can be a reliable surrogate to track the level of hydration, even walking, working or exercising even during everyday activities,” Jankovich said.
To validate the device, the research team performed several experiments, including a diuretic-induced dehydration study and a 24-hour real-life testing.
Participants were given medicines to promote fluid damage. Their hydration levels were monitored through wearable and compared to urine samples.

The device showed a strong connection between ARM bioemplines and change in total body water loss, SWNS. The findings were published in the proceedings of the National Academy of Sciences.
New sensors can provide a accessible and wearable option for traditional hydration tracking methods, such as urine or blood analysis, which are aggressive, time consuming and impractical, the researchers said.

Hydration is considered necessary to regulate body temperature, maintain organ function and support many other important processes.
Even mild dehydration can deteriorate concentration and performance, while severe dehydration can cause serious health problems such as heatstroke, kidney stones and cardiovascular issues, according to experts.

Beyond the use of everyday, researchers believe that technology can benefit patients with chronic dehydration, kidney disease or heart conditions. Athletes, also, can use wearable to stay safe and to perform better in especially in hot weather.
Severe dehydration can lead to serious health problems such as heatstroke, kidney stones and cardiovascular issues.
While the current model tracks relative hydration changes, Professor Lu said that the team’s purpose is to develop reference data for absolute hydration levels.
They are also looking for more advanced wearable format, such as breathable electronic tattoos or sweat-absorbed patch, to increase comfort during prolonged use.

“This is just the beginning,” Professor Lu said, according to the SWNS report. “Our goal is to make simple hydration monitoring accessible to all.”
