Woven Electrochemical Transistors on Silk Fibers



original image

Woven electrochemical transistors on silk fibers from the silkworm Bombyx mori are demonstrated. This is achieved with carefully chosen electrolyte chem-istry: electrically conducting silk fibers are produced by dyeing silk fibers with a conjugated polyelectrolyte and gating is accomplished by use of an electro-lyte mixture composed of imidazolium-based ionic liquids.
