Ask for the Number One
A battery that runs on urine? Absolutely:
Dr Ki Bang Lee, who heads the research team at the Institute of Bioengineering and Nanotechnology in Singapore, said: "We are striving to develop cheap, disposable, credit-card-sized biochips for disease detection. Our battery can be integrated into such devices, supplying electricity upon contact with biofluids, such as urine."
No, this isn't for your iPod:
The paper-thin device is designed to run cheap, disposable test kits for diseases such as diabetes. Many such tests use the chemical composition of urine to reveal signs of disease.
The new battery will allow the urine being analysed to provide the electricity needed to run the test kit, without having to rely on lithium batteries or external power sources.
Downright ingenious. My congratulations to the whiz kids who thought this up.
