“…For instance, a study on the effect of the alkyl chain length in alkylbenzenesulfonate dopants showed that the medium sized octylbenzenesulfonate gave the largest strain [35]. By exchanging the dopant BF 4 for CF 3 SO 3 the strain of PPy increased to 12% [36] and by switching to bis(trifluoromethanesulfonyl)imide as the dopant the strain increased further to 26% [37]. Apart from these more exotic ions, typical dopant ions used are DBS [9,38,39], PF 6 [32,40], BF 4 [41], and ClO 4 [19].…”

“…Hysteresis in the displacement of trilayer actuators has been suggested to be minor [4], although more characterization is required. Modification of the actuator chemistry, particularly the dopant, has been shown to improve the speed and magnitude of polypyrrole films actuation [11]- [13]. Applying control techniques to the actuator displacement shows strong potential for further performance improvement without adjusting the chemistry.…”

Abstract-Conducting polymer bending actuators show potential for unique manipulation devices, particularly at the microscale, given low actuation voltages, controllable manufacture, biocompatibility, and ability to operate in either air or liquid environments; however, the impracticalities of implementing feedback in these environments and at these scales can impede positional control of the actuator. This paper presents an application of inversionbased feedforward positional control to a trilayer bender actuator, which is shown to improve the performance without the use of feedback or adjustments to the chemistry of the device. The step and dynamic displacement responses have all been improved under the feedforward control system, while the response does not change significantly under large increases in external loads. This study contributes the first implementation of inversion-based feedforward control to the emerging area of conducting polymer actuators, paving the way toward their use in functional devices, particularly where the implementation of feedback is difficult.

“…This phenomenon is due to the different surface situations of solution and electrode sides of the films. Figure I shows the difference between two sides [5]. A mathematical model is needed to describe the bending actuation (especially for the tip deflection) for the further research …”

Abstract-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.
