“…(1) Without loss of generality, it is assumed that the electric resistances and ionic resistance are not constant. In fact, this electronic nonlinear characteristic has been observed in [15], which implies that the values of those resistances depend on the local charge.…”

“…The change interval affects the corresponding time of the actuator, so the nonlinear characteristics of the material are a consideration that can not be ignored in the modeling. [15] has proposed a finite nonlinear 2D-RC model, where this model takes into account the nonlinear characteristics of material properties following changes in charge density. In the work of Nishida [16], the infinite RC circuit was used to approximate the real system and finite difference method was adopted to get the numerical solution.…”

Conducting polymer actuator has nonlinear dynamic characteristics during its charge process. In this study, we proposed an electromechanic model and an optimal controller for a type of ionic electroactive polymer (IEPA) actuator with sub-millimeter scale, which can produce large deformation under low actuation voltage. The electronic model is to describe the evolution of charge state in time domain. The mechanic model is to calculate the deformation of conducting polymer actuator under the actuation force and external force. Based on the electromechanic coupling model, a parameter identification method is proposed to estimate the nonlinear parameter of conducting polymer actuator. The experiments show that our electromechanic model successfully predicts the deformation of actuator under different input voltages with the identified parameters. In the last step, an optimal controller is designed to control the orientation of IEAP actuator, which achieves at a high control performance in our experiments. The success of the modeling and control lays the foundation work for the subsequent biomedical applications.

“…Another limitation of freestanding conducting polymer actuator is the notable strain gradient especially for long conducting polymer strips when only one end is connected to the electrical source. The applied voltage attenuates longitudinally due to electronic resistance, resulting in the bottom part generating smaller strain and slower speed than its upper section [44,58].…”

“…Monolithic and bilayered implementations are primarily used in applications involving a supporting liquid electrolyte (either aqueous or organic), while trilayered ones are employed with an ionic gel electrolyte sandwiched between two PPy films for operation in air [ 23 , 99 , 100 , 101 ]. Due to longitudinal voltage attenuation along a semiconducting CP strip, a monolithic electroactuator’s tail usually generates smaller strain than its upper section [ 72 ], resulting in a notable strain gradient along the strip ( Figure 2 b). Another limitation of monolithic CP electroactuators is the time hysteresis on strain generation due to inherent mechanical resistance, which prevents their use in high-speed applications.…”

Featuring controllable electrochemomechanical deformation and excellent biocompatibility, polypyrrole electroactuators used as artificial muscles play a vital role in the design of biomimetic robots and biomedical devices. In the past decade, tremendous efforts have been devoted to their optimization on electroactivity, electrochemical stability, and actuation speed, thereby gradually filling the gaps between desired capabilities and practical performances. This review summarizes recent advances on polypyrrole electroactuators, with particular emphases on novel counterions and conformation-reinforcing skeletons. Progress and challenges are comparatively demonstrated and critically analyzed, to enlighten future developments of advanced electroactuators based on polypyrrole and other conducting polymers.
