The paper presents the initial results on the performance of cellulose-based Electro-Active Papers (EAPap) as actuators. The electro-active papers depend on ion migration and dipole moment for the actuation. EAPap is fabricated by depositing gold electrodes on the top and bottom surfaces of cellophane sheets. Small sheet specimens measuring approximately 1 cm × 3 cm, suspended from the 1 cm width were tested in this study. The characteristics of EAPap are evaluated by applying electric fields at different exciting frequencies and humidity levels. The dynamic responses of the specimens were measured using a scanning Laser vibrometer. As expected, different plate modes are excited at different frequencies. Wide variations in the performance of the specimens were seen bat different levels of humidity. The results indicate the potential of EAPap for low power and lightweight actuation.
