Development And Characterization Of The Ionic Polymer Metal Composite Actuated Contractile Water Jet Thruster

Ionic Polymer Metal Composite (IPMC) is a type of smart material that can be utilized as the actuator for contractile water jet thruster (CWJT) which is an alternative thruster for autonomous underwater vehicle (AUV). The advantages of IPMC actuator are light, flexible, able to be utilized underwate...
