Scientists harness the power of pee

Monday 15 August 2005

Physicists in Singapore have succeeded in creating the first paper battery that generates electricity from urine. This new battery will be the perfect power source for cheap, disposable healthcare test-kits for diseases such as diabetes. This research is published today in the Institute of Physics’ Journal of Micromechanics and Microengineering.

Scientists in research groups around the world are trying to design ever smaller “biochips” that can test for a variety of diseases at once, give instant results, and, crucially, can be mass produced cheaply. But until now, no one has been able to solve the problem of finding a power source as small and as cheap to fabricate as the detection technology itself.

Led by Dr Ki Bang Lee, a research team at Singapore’s Institute of Bioengineering and Nanotechnology (IBN) have developed a paper battery that is small, cheap to fabricate, and which ingeniously uses the bio-fluid being tested (e.g. urine) as the power source for the device doing the testing.

The chemical composition of urine is widely used as a way of testing for tell-tale signs of various diseases and also as an indicator of a person’s general state of health. The concentration of glucose in urine is a useful diagnostic tool for diabetics. The lead researcher, Dr Lee, envisions a world where people will easily be able to monitor their health at home using disposable test-kits that don’t need lithium batteries or external power sources.

Dr. Lee said: “We are striving to develop cheap, disposable credit card-sized biochips for disease detection. Our battery can be easily integrated into such devices, supplying electricity upon contact with biofluids such as urine.”

The battery unit is made from a layer of paper that is steeped in copper chloride (CuCl) and sandwiched between strips of magnesium and copper. This “sandwich” is then held in place by being laminated, which involves passing the battery unit between a pair of transparent plastic films through a heating roller at 120ºC. The final product has dimensions of 60 mm x 30 mm, and a thickness of just 1 mm (a little bit smaller than a credit card).

Writing in the Journal of Micromechanics and Microengineering, Lee describes how the battery was created and quantifies its performance. Using 0.2 ml of urine, they generated a voltage of around 1.5 V with a corresponding maximum power of 1.5 mW. They also found that the battery performances (such as voltage, power or duration) may be designed or adjusted by changing the geometry or materials used.

“Our urine-activated battery would be integrated into biochip systems for healthcare diagnostic applications,” says Lee. He envisions a world where people will easily be able to monitor their health at home, seeking medical attention only when necessary. “These fully-integrated biochip systems have a huge market potential,” adds Lee.

That is actually pretty cool. One night out boozing and I could light a city block!

When speaking of the MMOG industry, the glass may be half full, but it's full of urine. HaemishM
