“…Delamination initiated by repeated volume change at the interface causes irreversible deterioration of actuator performance. To resolve the problem of delamination, Vidal et al proposed a new actuator concept, that utilised an interpenetrating polymer network (IPN) consisting of embedded conducting polymer [5,6]. Khaldi et al demonstrated fabrication of microactuators made up of such IPN [7].…”

“…chemical [5][6][7][8][10][11][12] and electrochemical [1][2][3] synthesis routes for the preparation of organic polymer actuators. While most of the PPY actuators have been synthesized by electrochemical routes [1][2][3], most of the PEDOT actuators have been synthesized by chemical routes [5][6][7][8][10][11][12]. To date there has been no systematic study of the effect of synthesis method on the actuation performance.…”

The stress gradient generated due to electrochemical oxidation/reduction of a conducting polymer in a bilayer actuator causes a bending movement. Here we report a comparative study of the displacement of bilayer actuators prepared using different conducting polymers. The effects of conducting polymers obtained from electrochemical or chemical synthesis route: different polymers (polypyrrole (PPy), poly(3,4-ethylenedioxythiophene) PEDOT and poly(3,4b][1,4]-dioxepine [PProDOT(Hx) 2]); and different electrolytes (0.1 M lithium trifluromethanesulfonate/ propylenecarbonate (LiTFSI/PC) and 1-ethyl-3-methyl imidazolium trifluromethanesulfonate (EMITFSI)) on the displacement amplitude and displacement patterns of these actuators were investigated and compared. The results indicate that the bilayer actuator consisting of an electrochemically synthesized conducting polymer exhibits far greater displacements compared to chemically synthesized polymers at the same stimulating voltage. Similarly, amongst the three conducting polymers considered, the PPY actuator showed greater displacement followed by PProDOT and PEDOT. Furthermore, the use of different electrolyte solution during polymerization as well as during actuation was found to affect not only displacement distance but also its pattern.

Dimensional changes in conducting polymers such as polypyrrole (PPy), polyaniline (PANI), and poly(3,4-ethylenedioxythiophene) (PEDOT) during oxidation and reduction have been used for over 15 years to create movement, an actuating effect. This has opened up the possibility of the development of a new class of polymer-based, large strain, artificial muscles, to stand alongside other prospective materials, such as dielectric elastomers, shape-memory alloys, and carbon nanotube fibers [1]. Advantages of conducting polymers over more established actuator technologies, such as piezoelectric polymers, are seen in their low operation voltages, high work densities per cycle, and force generation capabilities, but with limitations seen in cycle life and energy conversion efficiencies [2].However, a complete picture of the volume changes at work in conducting polymers has yet to be determined [3], and it is widely recognized that an understanding and better exploitation of nanostructural aspects of conducting-polymer actuators will be necessary to improve their performance as required for practical applications [4][5][6][7]. In this chapter we will outline the main mechanisms of actuation which have been investigated for conducting-polymer actuators, along with recent research to model actuator performance and develop applications.

“…Guo et al added also a floating actuator to control the buoyancy of the micro robot and two "walking" actuators to advance along the basin of the vessel. A similar actuator was developed by Vidal et al [22] based on ECP (Electro Conducting Polymer). Nakabo et al [23] used IPMC to build a swimming actuator that creates an undulating motion.…”

We review micro-systems with robotic aspects that are used in medical diagnosis and intervention. We describe the necessary components for a microrobot and present the state of the art and gaps of knowledge. One of the great challenges in micro robots is the propulsion. Different propulsive strategies and specifically flagellar propulsion is evaluated in this chapter. We analyze the influence of the miniaturization on the micro-robot and try to estimate the future developments in the field.
