Abstract

As a novel piezoelectric material, the mechanical and piezoelectric properties of cellulose electro-active paper (EAPap) were studied. Young's modulus of piezoelectric EAPap was dependant on the material orientation as compared with other EAP materials. The highest Young's modulus was obtained at 0° direction, while the highest direct piezoelectric charge constant was achieved at 45°. By measuring the induced output voltage from the thin piezoelectric cellulose film under the applied impact force, we demonstrate that piezoelectric EAPap film has a potential for sensor applications.
