Bio-degradable EAPap Actuators

초록

Electro-Active Paper(EAPap) actuator materials based on cellulose are attractive for many applications because of their low voltage operation, lightweight, dryness, low power consumption, bio-degradable. The construction of electromechanical actuator has been achieved using the cellulose paper film coated with thin electrode layers. To understand the actuation mechanism, electrical behaviors of this EAPap was studied by taking into account ionic movement, electrical conductivity and dielectric property. This actuator showed a reversible and reproducible bending movement. In order to improve both force and displacement of this, EAPap actuator efforts are made to construct the device using increasing number of complementary conducting polymer layers and carbon nanotubes. EAPap are bio-degradable, which is important point for achieve artificial muscle actuators for biomimetics with controlled properties and shape.
