Electro-Active Papers based on Cellulose

초록

Electro-Active Paper (EAPap) is attractive for EAP actuator due to its merits in terms of lightweight, dryness, large displacement output, low actuation voltage and low power consumption. EAPap actuator has been developed based on cellulose material. Several kinds of cellulose are used for EAPap actuators and the performance of EAPaps is investigated in terms of displacement along with frequency, voltage, temperature and humidity. To investigate the actuation principle, electrical impedance measurement is conducted and results are compared with conducting polymer and piezoelectric ceramic materials. The principle that dictates the actuation of EAPap is discussed. Since the power requirement of EAPap is so small that it can be activated by remote microwave power, which is promising for making flying objects.
