Conducting polymer patterns are grown through flexible substrates using directional electropolymerization. An isolating gel layer between a polycarbonate membrane and a patterned anode allows reproduction of sub-ten-micrometer features (see Figure) throughout the volume of the membrane to the opposite side.
