Paper Abstract

The possibility as a vibration sensor of Electro-Active paper (EAPap) based on piezoelectricity was investigated in the present paper. The EAPap was fabricated by regenerating and tape casting cellulose. The gold, silver and aluminum were deposited on both sides of the cut cellulose film using a thermal evaporator. The sample was coated by thin laminating film for packaging. The simple aluminum cantilevered beam was used for the vibration testing and EAPap was attached on the beam. The original EAPap sensor without grounding and shielding has greatly affected by the surrounding noise such as power noise especially. The power noise reduced dramatically with grounding and shielding of EAPap. The impulsive response of EAPap provided correct dynamic characteristics of the beam. Forced response of EAPap presented that gold and silver electrodes are suitable for EAPap sensor but aluminum electrode provides too many noise due to high resistance. PVDF provided similar characteristics of EAPap, which results EAPap has high potential as a vibration sensor.
