Scientists Make "Holy Grail' Discovery To Charge Devices Using People's Bodies.

Scientists have invented the world's most efficient on-body energy harvester, capable of powering devices from a person's fingertips. Engineers at the University of California San Diego discovered that a thin, flexible strip placed on the skin could generate enough electricity from a wearer's sweat to power wearables and other devices. The goal is that this wearable will naturally work for you and you don't even have to think about it. Professor Wang and other authors of study detailing the system described it as the " holy Grail" of energy harvesters as it does not rely any external, irregular energy sources like sunlight or movement. As part of their experiment, the researchers used the device to power a Vitamin C sensing system, but claim that it could be adapted to power health and wellness like glucose meters. We want to make this device more tightly integrated in wearable forms like gloves' Mr Yin said.
