A new medical invention is about to surprise people with its unique nature to examine the patient’s health, which would require not much effort but just merely putting on a device. A rare device called wearable monitor could collect data from various chemicals in body sweat for measuring health indicators such as heart rate and body temperature. The device would assist in keeping eye on conditions such as dehydration and fatigue, according to one of the inventors, Ali Javey, electrical engineer at the University of California, Berkeley.

The system was described by the inventors in the Journal Nature. Accordingly, the sensor has an alarm-like feature which makes patients aware when it is time for body to have water and medications. Javey along with his associates used flexible plastic substrates to make the device, a flexible circuit board containing 10 circuit chips, connected to five sensors which can collect information about glucose, lactate, sodium, potassium levels and many other factors. The signals from the device can be transferred to a Smartphone app developed by the team, which would synchronize the data collected through sensors.

While many researchers are developing a similar sort of sensor for sweat, this already developed device could analyze multiple chemicals in sweat at a molecular level and it also transmits measurements.

“We only looked at four different chemicals, but sweat contains much more useful information that tells about what’s happening to the body, lots of studies have shown how and why sweat composition changes, but it was very difficult before to measure this on patients, the beauty of this is that it is a comfortable and easy-to-wear system”, said Dr. Javey. The inventors have filed a patent application for their first fully integrated electronic system that can continuously and simultaneously monitor multiple sweat chemicals.
