Researchers Power an ARM Processor for a Year Using Algae
A team of researchers at the University of Cambridge successfully replaced a battery with algae to provide continuous power to a microprocessor. The tiny system is roughly the same size as an AA battery and runs an ARM Cortex M0+ processor. However, rather than sipping power from a rechargeable battery, the researchers used a non-toxic blue-green algae called Synechoycystis to naturally harvest energy when exposed to the sun through photosynthesis.
