This research is funded by the U.S. Army Combat Capabilities Development Command Army Research Laboratory. This project is a perfect example of using a living system to generate electricity. Thus devised system won’t require any battery and can operate without any human input. The same research team discovered that electricity can be generated from the ambient environment/humidity with a protein-nanowire-based Air Generator (or ‘Air-Gen’). These protein nanowires were extracted from Geobacter, which are capable of generating electricity through water vapors in the air. Air-Gen is connected to these nano-wires to induce electricity. Interestingly, these nanowires can be used to create memristors, small brain-like devices for computations at very low electricity consumption. Memristors are considered children of neuromorphic processors. Read more.
