ActiPatch 3.0 could be Powered by Sweat
Sweat Powered Battery for Wearable Medical Devices
AUGUST 25TH, 2021
Researchers at Nanyang Technological University in Singapore created a flexible battery that is powered by sweat. The device could provide a new way to energize medical wearables, some of which already use sweat to detect or monitor disease. The stretchable device incorporates silver flakes that clump together and generate a small electrical current in the presence of sweat.
The new battery uses sweat as a power source. Sweat is rich in chloride ions, and it is this property that the battery exploits. It consists of a stretchable fabric onto which the researchers deposited ink containing silver flakes, to act as electrodes. The acidity and chloride ions in sweat cause the flakes to clump, resulting in an electrical charge. Because it can store absorbed sweat for long periods, the battery can generate power even when someone isn’t exercising and actively sweating.
“Our device could be more durable than current technology, as we showed it could withstand strain from a wearer’s daily activities, and repeated exposure to stress or sweat,” said Lee Pooi See. “The slim size of our battery also solves two problems in wearable tech: traditional button batteries are a problem for achieving the sort of sleek aesthetics that are attractive to consumers, while thinner batteries reduce the item’s ability to carry enough charge to last throughout the day.”
