Polymer actuator device system

1. A polymer actuator device system comprising:

a polymer actuator, which includes an electrolyte layer, a first electrode layer and a second electrode layer provided to oppose each other with the electrolyte layer interposed therebetween in a thickness direction of the electrolyte layer, and wherein the polymer actuator deforms in response to a voltage between the first and second electrode layers; and

a sealing member, which coats an entirety of the polymer actuator to be enclosed therein,

wherein the sealing member has two layers of a resin layer and an inorganic layer,

a thickness of the sealing member is 1 to 5 microns, and

an outer side of the sealing member in the thickness direction has a wear preventing body.

2. The system according to claim 1 ,

wherein the wear preventing body is provided at at least any of a support part of the polymer actuator device system and an application part which is driven in the polymer actuator device system.

3. The system according to claim 1 , further comprising:

a first terminal, which is electrically connected to the first electrode layer to apply the voltage thereto, and a second terminal, which is electrically connected to the second electrode layer to apply the voltage thereto; and

a structure interposed between the first and second terminals,

wherein portions of the first and second terminals and at least a portion of the structure are covered with the sealing member.

4. The system according to claim 1 , wherein a portion of the sealing member has a bellows shape.

5. The system according to claim 1 , further comprising:

an absorber, which is provided between the polymer actuator and the sealing member and absorbs moisture.

6. The system according to claim 5 , wherein:

the absorber is a granular powder,

one side of the sealing member has an adhesive layer which causes the sealing member to adhere to the polymer actuator, and

the absorber is provided on a side of the sealing member of the adhesive layer.
