Paper Abstract

The voltage creep behavior on actuation performance of cellulose based electro-active paper (EAPap) has been studied. Because the actuation of EAPap is originated from both the inner ionic movement in cellulose and its piezoelectric behavior, the actuation can be affected by the external field. When the external field applied, cyclic hysteresis of P-E loop is observed. In order to investigate the detail of actuation behavior of EAPap actuator, the detail actuation response - called voltage creep- is required. The voltage creep which can reduce the response and the actuating accuracy of actuator is one important issue in order to control the micro/nano scaled positioning of smart material devices. In this paper, we present the voltage creep phenomena of EAPap, which will give more detail information to understand EAPap as well as other polymer based smart materials.
