RESEARCHERS at the Nanyang Technological University (NTU) have developed a battery that could use sweat to power wearables such as smart watches and fitness trackers.

The team of three scientists showed that a prototype of the battery was able to power a temperature sensor and send data to a smartphone through Bluetooth.
