Research and Developments of Medical Devices using Soft Actuators by Conducting Polymers

导电聚合物，聚吡咯（Ppy），被用作软致动器的目标材料。研究发现，电解液对Ppy膜电极位置的调节选择了阳极膨胀和阴极膨胀之间的驱动特性。在一个膜上的阳极和阴极膨胀层的杂交证明了增强的双压电晶片致动。该致动器在（1）双有源层、（3）无缝界面和（3）可图案化性方面上级传统的双压电晶片致动器。这种新型的双压电晶片驱动器将软驱动器的应用领域扩展到仿生器件中。

Conducting polymer, polypyrrole (Ppy), was used as the target material for soft actuators. It was found that the tuning of electrolyte for electrode position of Ppy film selects the actuation characteristics between anodic expansion and cathodic expansion. The hybridization of anodic and cathodic expansion layers on one film demonstrated the enhanced bimorph actuations. This actuator is superior to the conventional bimorph actuators as the points for (1) double active layers, (3) seamless interface and (3) patternability. This new bimorph actuator will expand the application field of soft actuators into the biomimetic devices.
