glucose battery: bio battery developed by sony
Sony has developed a bio-battery that uses glucose to generate enough electricity to power a Walkman. The technology breaks down sugar in the carbohydrates using enzymes as the catalyst. The bio-battery reached a 50 milliwatt power output, the world's highest for passive-type bio-batteries, a major innovation. Reactive substances like glucose and oxygen, are absorbed into electrodes through natural diffusion rather than by force. A flow of electrons through the cathode and anode produces the power. The technology holds great promise as a clean energy source because sugar is produced naturally by plants through photosynthesis.
