Abstract

Cellulose paper is used as a basis of Electro-active paper (EAPap) actuator. EAPap actuator is a new and promising biomimetic actuator due to its characteristics of lightweight, biodegradable, dryness, large displacement output, low actuation voltage and low power consumption. EAPap is a complex anisotropic material, which has not been extensively characterized and additional basic testing is required before developing application devices. Therefore, mechanical properties of EAPap are investigated in this work under different environmental condition such as humidity and temperature. The pulling test results provide that the humidity and temperature heavily impact the mechanical properties of EAPap. Electro-mechanical coupling effects are also investigated by applying electric field during the pulling test. Strong shear electro-mechanical coupling effects are observed when comparing relative increment of mechanical properties under electric excitation. It is concluded that strong shear piezoelectricity of EAPap actuator are existed.
