This paper investigates a biomimetic electro-active paper (EAPap) actuator driven by microwave power. EAPap made with cellulose paper is interesting and promising material for biomimetic actuators due to its characteristics in terms of lightweight, biodegradable, dry condition, large displacement, low actuation voltage and low power consumption. EAPap actuator exhibits a bending deformation in the presence of electric field, which can be used for biomimetic applications. But power supply is a problem because the EAPap actuator couldn't carry on battery. Microwave power transmission (MPT) is a feasible method for resolving the power supply problem. Rectifying antenna (Rectenna) that consists of rectifying circuit and antenna, is a key element for MPT. This paper illustrates the rectenna fabrication on cellulose EAPap and its demonstration by microwaves. Also, the characterization of rectenna on cellulose is performed in terms of receiving voltage, power along with the distance of microwave transmitter.
