Cover: . Polypyrrole, a promising conducting polymer, can be micropatterned through high‐frequency pulses of extremely miniaturized electrical discharge generated on it. Fine micromachining with a controlled depth of 7.5μm and an average surface roughness of 70 nm is demonstrated. The process is found to cause no major alteration in the material composition. Fabrication of polypyrrole electrodes/actuators on medical catheters is also demonstrated.
