Abstract A bilayer structure (polypyrrole/flexible and inactive polymer) was constructed. Reverse conformational changes promoted along polypyrrole chains during electrochemically induced oxidation-reduction processes were transformed to macroscopic angular movement of the bilayer. The movement of devices having different areas or different thicknesses of polypyrrole were quantified at different current densities. At all different device dimensions the movement rate was a linear function of the applied current per milligram of polypyrrole. The consumed electrical charge per milligram of polypyrrole to deflect through a constant angle was independent of the applied current density. At the same time the consumed electrical energy per milligram of polypyrrole increases linearly as a function of the applied current.Thus the movement rates, consumed charges and energies are not controlled by dimensions but by the masses of electroactive material.
