“…On the basis of the ER effect and special mechanic properties, EREs can be applied in several fields, including dampers, automotive industries, building base-isolation, and smart skins in bionic technology [12,49]. Although commercialization of ERE-based devices has not been implemented, the tentative application of EREs has been done in some laboratory research studies.…”

Electrorheological elastomers (EREs) are smart elastomers with tunable dynamic properties by applying electric field. They are composed by polarizable particles dispersing within elastomers matrix. In comparison with electrorheological fluids, the particles in EREs do not undergo aggregation and sedimentation. Without the requirement of largesized electromagnetic coils, the smart devices based on EREs have simpler structures than those based on magnetorheological (MR) elastomers. The unique properties and merits of EREs give rise to their bright future in various fields. During the past decades, great progress has been made by scholars around the world. In this chapter, the conception, preparation, physical mechanisms, classification, development, influence factors, and applications of electrorheological elastomers is reviewed.

“…In view of their composition and physical states, EREs can be considered solid analogues of ER fluids . In contract to that of ER fluids, the ER effect of EREs is expressed as the electric field controlled dynamic viscoelasticity; their storage modulus, loss modulus, and damping factors can be changed reversibly and quickly through the application of different electric fields . Because the carrier liquid of ER fluids is replaced by a polymer matrix in EREs, the sedimentation of particles and the leakage of liquid are avoided.…”

Electrorheological elastomers (EREs) present a tunable viscoelasticity with the application of an electric field. For their application, it is necessary to investigate the viscoelasticity of the EREs under various loading conditions and establish an accurate constitutive model. In this study, anisotropic silicone-rubber-based EREs with 30 vol % TiO 2 -urea core-shell particles were prepared under an orientation electric field. We evaluated their viscoelasticities by testing their shear stress-shear strain hysteresis loops under various electric fields, frequencies, and strain amplitudes. On the basis of the experimental data, a nonlinear, revised Bouc-Wen phenomenological model was established, and the parameters in the model were identified. The results indicate that the revised model could accurately describe the viscoelastic properties of the EREs within a low frequency.

“…Therefore, this phenomenon is called the electroadhesive effect (EA effect; Kakinuma et al, 2005Kakinuma et al, , 2010 Due to the unique functionality, it is expected to apply the ER gel to several devices such as clutch, damper, and fixture device. Figure 1 shows the structures of these application devices (Kakinuma et al, 2006(Kakinuma et al, , 2007. When ER gel is applied to a clutch or a brake as shown in Figure 1(a), a master metal disk with ER gel sheet is put on a slave metal disk.…”

ER gel exhibits various adhesive characteristics according to the applied electric field. This characteristic is called the EA effect. The results of a recent study reveal that the EA effect also occurs in a vacuum. Therefore, it is expected that ER gel can be applied to a chucking or damping device in a vacuum process. However, the characteristics of ER gel in a vacuum have not been sufficiently clarified. The purpose of this study is to experimentally evaluate the characteristic of ER gel in a vacuum. The performance of an ERG fixture element used for a silicon wafer in a vacuum is evaluated through shearing tests. The experimental results indicate that the ER gel demonstrates satisfactory performance in a vacuum. Moreover, the outgas released from the ER gel in a vacuum is evaluated, and the influence of the degassing time on the outgas is investigated.
