Abstract. The usage of Ionic Polymer-Metal Composite (IPMC) actuator as the propulsor for underwater robot has been worked out by many scientists and researchers. IPMC actuator had been selected due to its advantages such as low energy consumption, low operation noise and ability to work underwater. This paper presents the fabrication and characterization of the IPMC actuator. The IPMC actuator samples had been fabricated using electroless plating for three different thickness and lengths. The characterization was conducted to determine the influence of the thickness, length, input frequency, drive voltage and orientation angle on the tip force and output frequency. The results show that IPMC thickness has significant influence on the tip force generation and lower input frequency would results wider displacement. The recorded results are essential as future reference in developing the propulsor for the underwater robot. Besides, IPMC actuator consumes low energy between 1V and 3V, depend of type of the task [7]. IPMC actuator has few other advantages such as low noise operation and large bending strain [8]. However, this actuator has constraints that should be considered in order to develop the underwater Introduction

“…The ejected water jet produces thrust in one direction and accelerates the thruster body in the opposite direction. It has low noise propulsion compared to the electric motor driven blade thruster if being actuated by smart actuator [2]. The function enables the CWJT to be adapted to quite or high sensitivity underwater task.…”

Abstract. This research was conducted to investigate the feasibility of Ionic Polymer Metal Composite (IPMC) as the actuator for Contractile Water Jet Thruster (CWJT). The thrust that generated from the accelerated volume of ejected fluid depends on the IPMC actuator contraction performance. During this investigation, the variation of contraction frequency and nozzle aperture influence on the body deformation was carried out. The results of the experiments exhibit that the body contraction decreased tremendously from 0.05 Hz to 0.15 Hz. The body contraction has no apparent decrement for more than 0.15 Hz of contraction frequency. Besides, larger nozzle aperture has relatively more body contraction than smaller nozzle aperture. These results show that the fixed actuation force and the contraction frequency have a significant influence on the CWJT body contraction.

In this paper, the authors present a comprehensive review of ionic polymer-metal composites (IPMCs) covering their fundamentals, fabrication processes, characterization and applications. IPMCs are becoming increasingly popular among scholars, engineers and scientists due to their inherent properties of low activation voltage, large bending strain -that is, the transformation of electrical energy to mechanical energy -and properties to be used as a bidirectional material -that is, they can be used as actuators and sensors. Among the diversity of electroactive
