An intelligent, light and wireless sensor arrives from the Penn State, capable of monitoring the water balance through sweat analysis: a useful device for athletes, patients
A team of researchers from Penn State University has developed a Innovative sensor wearable for hydration able to monitor body hydration levels in real time. Light, flexible and non -invasive, the device represents a step forward in personalized medicine and high performance sport.
The new wearable sensor works by analyzing human sweat, with particular attention to pH and the concentration of sodium. These two parameters are closely connected to the body’s hydration state. A variation of the pH can indicate dehydration, while the amount of sodium provides indications on the loss of electrolytes through sweat.
Unlike other similar devices, this sensor stands out for its ability to function wirelessly, continuously and in real time. In addition, it is made with economic and easily available materials, which favors one large -scale production It is also accessible to the general public.
A further new element is the integration of a microfluid system that collects sweat and conveys it towards a reaction chamber, where chemical analysis takes place. The signal generated is then transmitted via bluetooth to a smartphone or another mobile device for viewing data.
Research, applications and future impacts
The project, published in the magazine ACS SENSERSis led by Hunyu “Larry” Cheng, associate professor of engineering at Penn State. According to the research team, the sensor may have Numerous applications in the medical, sporting and military fieldsoffering constant monitoring of hydration in the most critical contexts.
In the field of personalized medicinethe sensor could help prevent complications linked to pathologies that influence the water balance, such as diabetes, kidney diseases or cardiovascular conditions. In addition, it could be used in healthcare facilities to monitor patients at risk of chronic dehydration.
For professional athleteson the other hand, the device represents a turning point. In fact, it allows you to accurately calibrate the intake of liquids and electrolytes, thus improving performance and reducing the risk of cramps, fatigue or performance drops.
Finally, the economic and scalable nature of technology opens the way to one possible Vast scale marketingmaking it suitable for daily use by common people interested in their well -being.
