human bodies could energise their electronic implants in the very near future. Chemists from Austin-based University of Texas have developed a miniature battery that could run on body fluids. The battery converts energy produced during metabolism into electricity. It could be inserted very easily next to glucose-containing body fluids found, for instance, under the skin or in the spinal cord.

The chemists claim their battery is medically useful, as it is tiny, produces adequate amount of power (same as the wristwatch battery
