Kind Code:

Abstract:
[Problem] Properties necessary for an electroactive polymer material that is used in a transducer device include dielectric breakdown strength, Young's modulus, dielectric constant, thickness and electromechanical instability; and these properties have a correlation with each other. The correlation among these properties, however, has not been defined yet and thus a huge amount of effort is required to find excellent materials for an optimum electroactive polymer material by trial and error, while an optimum electroactive polymer material that satisfies all requirements has not been achieved. [Solution] The above are achieved by means of a curable elastomer composition which contains a compound having a highly dielectric functional group, and a cured product of which satisfies formula AA (wherein E represents a dielectric breakdown strength within the range of from 50 V/μm to 200 V/μm; α represents a constant within the range of from 0.4 to 0.9; Y represents a Young's modulus within the range of from 0.001 MPa to 10 MPa; εγ represents a relative dielectric constant of 100 or less; and ε0 represents the dielectric constant of vacuum).
