The Korvaa Microbe-Grown Headset is a concept design—for now. This experimental creation of microbe-grown headphones is the result of a collaboration between scientists and designers. They’ve explored how design and biologically based materials can work together in ways they never have before. This bio-based headset comes from the new technology of Synbio, which stands for Synthetic Biology. Designers crafted these headphones by engineering biological organisms into useful items. It might seem like we’re in a science fiction world when we start using synthetic organisms as electronic devices. But it actually has the potential to help us move away from fossil fuels and into a more “circle of life” world. Korvaa combines foam-like solid materials to create a new type of listening device.
