To obtain this novel fiber, the research team combined bagworm silk with polyaniline as a conducting polymer. The composite fibers act as an optical waveguide and are suitable for use in textile transistors. This production of a bagworm silk/polyaniline composite will enable the use of biocompatible conducting fibers for applications ranging from microelectronics to biomedical engineering.
