This paper characterizes and models the bending motion of the strip-type Ionic Polymer Metal Composites (IPMC) actuators using the theory of Large Deflections of Beams. From here it derives a thermal analogy.
The mathematical model has been experimentally verified for an actuator with the dimensions 25mm×2.6mm×0.44 mm.
Theoretical and experimental results are compared to show the validity of the model in predicting the displacement output of the strip type-IPMC actuator as a function of the applied voltage.
