HEALTHCARE TEST KITS GET URINE-POWERED BATTERIES

The Institute of Bioengineering and Nanotechnology (IBN), a Singapore scientific institute, said it has invented a urine-powered micro battery that can run cheap, disposable test kits for diseases such as diabetes. The state-funded institute said a drop of urine placed on the paper battery will generate enough electricity to power a "biochip device" that can analyze the urine sample for disease "biomarkers."
