Abstract
The present invention provides an actuator which uses a cationically conductive polymer electrolyte and shows a large deformation response. The actuator has a pair of opposing electrodes and an intermediate layer arranged between the pair of the electrodes, which actuator being curved and displaced when voltage is applied to the electrodes, wherein the intermediate layer has at least: the cationically conductive polymer electrolyte having an ether bond site and an anion site in its molecule; and a weakly acidic material which interacts with the ether bond site.
Claims7
An actuator having a pair of opposing electrodes and an intermediate layer arranged between the pair of the electrodes, the actuator being curved and displaced when voltage is applied to the electrodes,
- wherein the intermediate layer has at least:
- a cationically conductive polymer electrolyte having an ether bond site and an anion site in its molecule;
- and
- a weakly acidic material, which interacts with the ether bond site and which is different from the cationically conductive polymer electrolyte.
