For centuries scientists have dreamt with devices able to mimic the behavior of the biological organs. One of the key aspects of that behavior is the ability to sense the working conditions while actuating. This is due to the electrochemical reactions taking place in the intracellular matrix which provoke the exchange of ions and water with the surroundings. With the view to reaching that potentiality conducting polymers have been widely studied, they are reactive materials constituted by polymeric molecular motors giving multifunctional sensing-actuators whose working principles are the same that those of the biological cells. They are soft materials, containing macromolecules whose conformational movements allow ionic and water exchange. In this work polypyrrole/dodecyl benzene sulfonate (PPy/DBS) films were electrogenerated using different electrochemical parameters giving as a result polymer with different thickness whose mechanical and actuating properties were studied finding relationship between them and with the oxidation state that could lead to the production of conducting polymers with tailor-made properties.
