Title:
METHOD FOR MANUFACTURING DIELECTRIC ELASTOMER TRANSDUCER
Document Type and Number:
WIPO Patent Application WO/2019/146429
Kind Code:
A1
Abstract:
A method for manufacturing a dielectric elastomer transducer comprising a dielectric elastomer layer and a pair of electrode layers that sandwich the dielectric elastomer layer, wherein the stress-strain curve on the tension side of the dielectric elastomer layer has a low strain high elastic modulus region that includes a state in which the strain is zero and has a relatively large inclination, a low elastic modulus region that is connected on the high strain side to the low strain high elastic modulus region and has a relatively small inclination, and a high strain region that is connected on the high strain side to the low elastic modulus region and has a relatively large inclination or includes a breaking point, the method comprising: a pre-stretching step for reducing hysteresis in the elastic behavior of the dielectric elastomer layer by applying a load greater than or equal to a first load to the dielectric elastomer layer, prior to providing the pair of electrode layers, such that one or more elongation treatments generating a first tension of a magnitude included in the low elastic modulus region are carried out; and a dielectric elastomer layer fixing step for fixing the dielectric elastomer layer to a support member in a state in which a second tension lower than the first tension is generated by applying a second load lower than the first load to the dielectric elastomer layer after the pre-stretching step. Through such a configuration, it is possible to operate with higher reproducibility.
