Piezoelectric Fibers Form Fantastic Fabric

An optical fiber with a piezoelectric polymer coating suggests applications with a sci-fi quality
Department: Science & Technology
Keywords: piezoelectric, fibers, fabric, materials

An optical fiber with a piezoelectric component that can be woven into a fabric suggests applications with a sci-fi quality—clothing that acts as a microphone, meshes of sensors that monitor oceanic currents, or sensors that monitor blood flow inside tiny capillaries. Yoel Fink of Massachusetts Institute of Technology and colleagues have designed such fibers that not only transmit optical signals but vibrate in response to an electric current, or, vice versa, produce electric . . .
