Round the bend: Reversible bending of conducting‐polymer–gold nanowires is achieved by template synthesis and a selective coating process that leaves only one side of the polymer segment exposed. The bending motion of the resulting “nanofingers” can be tailored by adjusting the applied potential (see figure). This represents the smallest bending arm reported to date and the first example of electrochemically induced nanowire bending.
