| Outline of Final Research Achievements |
In this research, we proposed and developed a novel variable-stiffness ionic polymer-metal composite (IPMC) actuator for soft robotics in order to maintain IPMC deformation without its back relaxation.
A shape memory polymer (SMP) was used as a variable stiffness material by heating. From a result of experimental productions, IPMCs with SMP were able to maintain their deformation at room temperature. Also, a positive temperature coefficient (PTC) heater was used as a self-controlled heating material for heating SMP and it was confirmed that PTC heater was useful to realize the variable-stiffness IPMC.
Driving characteristics of the proposed IPMC was simulated by a 2D finite element analysis. Simulated results seemed qualitatively correct because their tendencies agreed with those of measurement results of the prototype IPMC with SMP.
