The desktop biofiber spinning machine, like a 3D printer, enables prototyping and experimenting with bio-based fibers. The fibers can be tuned with different properties and then spun to create yarns. Importantly, these fibers can be easily dissolved, enabling electrical components to be recovered and recycled. Smart textiles integrate electronic materials into knitted or woven structures. They are widely used in soft and conformal electronic systems for applications in fashion, robotics and medicine. However, smart textiles pose significant environmental risks because they combine two highly toxic waste streams: textile and electronics waste. This work explores creating and using sustainable bio-based fibers that support disassembly and electronics recyclability.
