Overview of the polymer actuator technology
There are two kinds (the ion conduction actuator and the electro conductive polymer actuator). |
| Ion conduction AC | electro conductive polymer AC | |
|---|---|---|
| Composition | ion exchange polymer + gold plating | Plypyrrole(conductive polymer) |
| Property | Composite material of soft regin and metal | Regidity film |
| Shape | ・0.03～5mm thickness film type rod type | ・0.01～0.1mm thickness film type ・Accumulating device of film ・Polypyrrole-metalcoil composites and bundle type ・Polypyrrole-zigzag metal wire composite film and multi layer type |
| Environment to be used | dry, in water, in polality solvent | dry, in water, in polality solvent |
| Applied voltage | 1～3V | 1～2V |
| Direction of operation | It operate in the horizontal direction of the actuator | It operate in the vertical direction of the actuator |
| Displacement | depends on thickness It bends by three rotations. (0.2mm thickness, 20mm length) | 40% Max 15% Min |
| Displacement rate | depends on thickness 5mm/sec (0.2mm thickness) | 10%/sec |
| Generation power | depends on thickness 5gf (0.5mm thickness, 5mm length) | 500kg/cm2 Max 50kg/cm2 Usually |
| Durability | 30 million times (1Hz) | four million times (It is continuing) |
| Use temperature | -20～80 deg | -20～80 deg |
