Sweat patch turns sweat into a charging source for your phone

American scientists have successfully created a skin patch that can use sweat to generate energy for phones.

Scientists at the University of California, San Diego, USA, have successfully created a skin patch that can convert sweat into energy, enough to power your phone while you jog, Mother Nature Network reported on June 22.

The skin patch is a flexible square just a few centimeters wide. It uses enzymes to convert lactic acid in sweat into energy. The team created a prototype that could power a radio for two days.

For biofuel cell technology, this result is quite impressive as the patch produces 10 times more energy than previous products.

Skin patch uses sweat to power phone.

"Now we've generated quite an impressive amount of power. If you go out for a run, your sweat can power a mobile device," said Joseph Wang, lead author of the study.

The patch could be a great way to keep your phone charged while you exercise, and researchers are also looking at ways to create biosensors that can monitor your health.

Sweat contains several important biomarkers. For example, glucose levels in sweat are similar to those in the blood. Therefore, diabetics can use patches to monitor their blood sugar levels.

“The most exciting application of the new technology is wearable health sensors. Sweat generates enough energy to enable Bluetooth connectivity, transmitting the resulting data directly to a smartphone,” said Mirella Di Lorenzo at the University of Bath, UK.
