This new cheap, disposable battery has a practical use in test-kits for Diabetes.
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.
