Conventional soft conductors are characterized by a large change in electrical conductance upon mechanical deformation. In a recent joint work with the Chair for Functional Nanotechnology (Prof. Adelung) we combine thin film deposition technologies in a three-dimensional fashion, resulting in multi-layered and ultra-lightweight foam-like framework structures based on poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate), coated with polytetrafluoroethylene. These all-organic soft conductors show strain-invariant conductance over a large strain range, super elastic deformation and water stability.
