Professor Angela Belcher, a biomolecular materials chemist at MIT, is trying to use biological methods, such as viruses, to assemble batteries. "The goal is to have biology make things in an environmentally friendly way," says Professor Belcher.
Professor Belcher's virus-assembled batteries are thin, transparent sheets that look like plastic wrap. They could be used to create smart credit cards or lightweight hearing-aid batteries. Eventually, Professor Belcher hopes to weave battery cells into textile fibers to create battery-powered fabrics for clothing. As an example, soldiers might plug night-vision goggles into their uniforms, instead of using traditional batteries for energy.
