Characteristics ICPF PVA PZT PVDF ISMA

he ionic conducting polymer gel film (ICPF) actuator, T which has advantages such as low driving voltage, high speed, and underwater motion, was discovered in 1992. This article presents a new actuator element using the ICPF which generates an elliptic motion, as used in ultrasonic motors, to drive objects by friction. A method of forming a pattern of ICPF on a membrane was developed for production of the element. Some robotic applications are proposed. Experimental elements effectively functioned as driving devices and successfully drove a rotary motor as a testimony. Experiments and modeling revealed the relationship of the resultant elliptic motion to control signals and design parameters.
