Abstract

The piezoelectric effect of electroactive cellulose has been studied. Hardwood and softwood papers were selected to estimate a bending actuation performance in connection with electromechanical coupling factors. The cantilever unimorph actuators are considered. The results show that the coupling is highly non-linear particularly at high k₃₁ for both papers but not at low k₃₁. The effect of the thickness ratio is a critical operating factor at lower k₃₁. In comparison of both appers, softwood paper showed larger coupling factors than that of hardwood paper due to lower Young's modulus affecting its stiffness as expected. The future study will center around the sensitivity analysis on the performance analysis of different types of electroactive cellulose actuators. Also, the temperature dependence of the coupling factors will be investigated due to the change of crystalline structure of cellulose in a form of paper.
