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

采用导电聚合物聚吡咯（Ppy）作为软致动器的靶材料。研究发现，电解液对Ppy薄膜电极位置的调节选择了薄膜在阳极膨胀和阴极膨胀之间的驱动特性。阳极和阴极膨胀层在同一膜上的杂交表明双晶型驱动增强。该致动器优于传统的双晶片致动器，因为(1)双有源层，(3)无缝接口和(3)可图案性。这种新型双晶片驱动器将软驱动器的应用领域扩展到仿生器件。

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.
