We present a novel strategy that for the first time produces three-dimensional (3D) PPy structures with high aspect ratios (HAR) via template free localized electrochemical deposition (LECD). This strategy, based on the accurate control of the moving electrode, consists in inducing the homogeneous generation of radicals on the grown structure during deposition. This enabled us to fabricate HAR (over 50:1) structures with different geometries -- from simple straight lines to structures with complex features. The practical cases presented here are of course only a few of the many different examples of conducting polymer HAR micro and nanostructures that our novel LECD approach can fabricate by appropriate tuning of the growth parameters.
