Aug. 15, 2005 -- Scientists in Singapore have invented a battery powered by urine. "We are striving to develop cheap, disposable, credit card-sized biochips for disease detection. Our battery can easily be integrated into such devices, supplying electricity upon contact with biofluids such as urine," says Ki Bang Lee, PhD, MS, in a news release... ...The battery sandwiches copper, paper laced with copper chloride, and magnesium between two plastic layers. The "sandwich" is later laminated. "When a droplet of human urine is added into the battery the urine soaks through the paper between the magnesium and copper layers. The chemicals dissolve and react to produce the electricity," write Lee and colleagues. In tests, the battery produced a maximum of 1.47 volts, dropping a bit with time but keeping a constant voltage of 1.04 volts for 90 minutes, write the scientists. The battery could be used in home-based health kits, they suggest... Debbi Gee Whiz! Maru __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
