Abstract: IPMC(ionic polymer metal composites) as a type of electro active polymer material has some disadvantages of low rigidity, non-desired output displacement, tiny actuating force and low withstanding voltage etc. A novel method was proposed to bond several pieces of IPMC strips together to form multi-layered n-IPMCs using conductive resin. Models of single- and multi-layered parallel connection IPMC micro-actuators were established based on finite element analysis method to predict their output characteristics. Double-layer IPMCs were then fabricated and characterized. The experimental results showed that the double-layer 2-IPMCs are significantly improved in aspects of output force, output displacement, stiffness, withstanding voltage and water retain property compared with that of the single-layer IPMC.
