We have proposed the flow control by using an artificial muscle based on the conducting polymer. In order to utilize the artificial muscle for flow control, it is important to clarify the mechanical properties on the artificial muscle based on the conducting polymer. The purpose of this study is to clarify the mechanical properties on artificial muscle and possibility of flow control by using it. We have measured the tensile force generated by artificial muscle in the distilled water. Moreover, we have observed the actuation of artificial muscle based on the conducting polymer in water tunnel. The tensile force of artificial muscle increased as the electrode potential increased. The averaged maximum tensile force did not depend on the scan rate of electrode potential. It depended on the electrode potential and was almost constant. However, the time for reaching maximum tensile force depended on the scan rate. The artificial muscle performed the bending actuation sufficiently not only static water but also running water. Therefore, it can be considered that the artificial muscle will be applied to the actuator for flow control.

This paper appraisals state-of-the-art dielectric elastomer actuators (DEAs) and their forthcoming standpoints as soft actuators which have freshly been considered as a crucial power generation module for soft robots. DEs behave as yielding capacitors, expanding in area and attenuation in thickness when a voltage is applied. The paper initiates with the explanation of working principle of dielectric elastomer grippers. Here the operation of DEAs include both physics and mechanical properties with its characteristics, we have describe methods for modelling and its introductory application. In inclusion, the artificial muscle based on DEA concept is also formally presented. This paper also elaborates DEAs popular application such as- Soft Robotics, Robotics grippers and artificial muscles.

Artificial muscle actuator has been devoted to replicate the function of biological muscles, playing an important part of an emerging field at inter-section of bionic, mechanical, and material disciplines. Most of these artificial muscles possess their own unique functionality and irreplaceability, but also have some disadvantages and shortcomings. Among those, phase change type artificial muscles gain particular attentions, owing to the merits of easy processing, convenient controlling, non-toxic and fast-response. Herein, we prepared a silicon/ethanol/(graphene oxide/gold nanoparticles) composite elastic actuator for soft actuation. The functional properties are discussed in terms of microstructure, mechanical properties, thermal imaging and mechanical actuation characteristics, respectively. The added graphene oxide and Au nanoparticles can effectively accelerate the heating rate of material and improve its mechanical properties, thus increasing the vaporization rate of ethanol, which helps to accelerate the deformation rate and enhance the actuation capability. As part of the study, we also tested the performance of composite elastomers containing different concentrations of graphene oxide to identify GO-15 (15 mg of graphene oxide per 7.2 mL of material) flexible actuators as the best composition with a driving force up to 1.68 N.

Abstract Electrically conductive cellulose-based hydrogels are prepared by a facile and environmentally friendly method, of which the electrical and mechanical properties can be easily controlled by varying the graphene loading. With an ultralow initial addition of graphene oxide (GO, 0.2 wt% versus the mass of cellulose), the resulting cellulose/reduced graphene oxide (CG0.2) hydrogel shows a significantly enhanced compressive modulus of 332.01 kPa, 54.8% higher than that of pure cellulose hydrogel. Further increasing the addition of GO to 2 wt% (versus the mass of cellulose), the electrical conductivity of the resultant CG2.0 hydrogel is as high as 7.3×10−3 S/m, 10,000-fold higher than that of pure cellulose hydrogel, and of which the mechanical properties are also enhanced. These cellulose-based hydrogels with controllable electrical and mechanical properties have a great potential for application in drug delivery and artificial muscle.

This paper presents a review of some of the applications for artificial muscle and several material of artificial muscle. We focus attention on the polymer material artificial muscle, which responds to electrical stimulation with a significant change in shape or size. Through our research on a variety of materials and the analysis of the mechanical properties of muscle movement, finally we designed the artificial muscle device the imitation of muscles stretching device. This article describes the structure and performance of the device.
