Several simple mathematical models are developed in this paper, which are used to describe the bending actuation of a single layer polypyrrole actuator, especially for the tip deflection. All the results are compared with the experimental result which was gotten in previous research. The Comparison result shows that the bending actuation of a single layer polypyrrole actuator can be describe by different simple functions. In these models, the third order polynomial model is most close to the experimental result and can be used for further works.
