The patch turns sweat into a charging source for the phone

US scientists have successfully developed skin patches that use sweat to power the phone.

Scientists at the University of California, San Diego, USA, have successfully developed skin patches that can turn sweat into energy , enough to power your phone to function normally while you are jogging, Mother Nature Network said on June 22.

The skin patch is a flexible square with a width of just a few centimeters. It uses enzymes to convert lactic acid in sweat into energy. The research team created a test product capable of delivering power to a radio station for two days. For biofuel cell technology, this result is quite impressive as the patch makes up 10 times more energy than previous products.

"Now we've created an impressive level of power, and if you go out to run, your sweat can power your mobile device," said lead researcher Joseph Wang. , said.

This patch can be a great way to keep your phone fully charged while you're exercising. Researchers also view this as a way to create a biological sensor that monitors users' health.

Sweat contains some important biological indicators. For example, the glucose concentration in sweat is equivalent to the concentration in the blood. Therefore, patients with diabetes may use patches to monitor blood glucose levels.

"The most interesting application of the new technology is the sensor that monitors the health status worn on the body. Sweat generates enough energy to connect Bluetooth, transmit data directly to the device. " said Mirella Di Lorenzo of the University of Bath, UK.
