Scientists harness the power of pee | |
A urine powered battery the size of a credit card has been invented by Singapore researchers.
A drop of urine generates 1.5 volts, the equivalent of one AA battery, says Dr Ki Bang Lee of the Institute of Bioengineering and Nanotechnology. He says the technology could provide a disposable power source for electronic diagnostic devices that test urine and other body fluids for diseases like diabetes. | |
