Ionic liquids (ILs) including ambient-temperature molten salts, which exist in the liquid state even at room temperature, have a long research history. However, their applications were once limited because ILs were considered as highly moisture-sensitive solvents that should be handled in a glove box. After the first synthesis of moisture-stable ILs in 1992, their unique physicochemical properties became known in all scientific fields. ILs are composed solely of ions and exhibit several specific liquid-like properties, e.g., some ILs enable dissolution of insoluble bio-related materials and the use as tailor-made lubricants in industrial applications under extreme physicochemical conditions. Hybridization of ILs and other materials provides quasi-solid materials, which can be used to fabricate highly functional devices. ILs are also used as reaction media for electrochemical and chemical synthesis of nanomaterials. In addition, the negligible vapor pressure of ILs allows the fabrication of electrochemical devices that are operated under ambient conditions, and many liquid-vacuum technologies, such as X-ray photoelectron spectroscopy (XPS) analysis of liquids, electron microscopy of liquids, and sputtering and physical vapor deposition onto liquids. In this article, we review recent studies on ILs that are employed as functional advanced materials, advanced mediums for materials production, and components for preparing highly functional materials.

“…By using highly deformable and stretchable materials, we can build robots that safely interact with human operators and function in unstructured environments such as debris fields or within the human body. To date, various types of soft robotic components have been demonstrated, including resistance-based sensors, [1][2][3][4] capacitance-based sensors, [5][6][7] ionic actuators, [8][9][10] pneumatic actuators, [11][12][13][14] and dielectric actuators. [15][16][17] Recent work on soft sensing technologies has employed liquid-metal-embedded elastomers to measure surface strain, 1,2,18 joint angles, 19,20 and applied pressure.…”

In this article we present mechanical measurements of three representative elastomers used in soft robotic systems: Sylgard 184, Smooth-Sil 950, and EcoFlex 00-30. Our aim is to demonstrate the effects of the nonlinear, time-dependent properties of these materials to facilitate improved dynamic modeling of soft robotic components. We employ uniaxial pull-to-failure tests, cyclic loading tests, and stress relaxation tests to provide a qualitative assessment of nonlinear behavior, batch-to-batch repeatability, and effects of prestraining, cyclic loading, and viscoelastic stress relaxation. Strain gauges composed of the elastomers embedded with a microchannel of conductive liquid (eutectic gallium-indium) are also tested to quantify the interaction between material behaviors and measured strain output. It is found that all of the materials tested exhibit the Mullins effect, where the material properties in the first loading cycle differ from the properties in all subsequent cycles, as well as response sensitivity to loading rate and production variations. Although the materials tested show stress relaxation effects, the measured output from embedded resistive strain gauges is found to be uncoupled from the changes to the material properties and is only a function of strain.

“…Especially, IPMC attracts attention as an actuator which makes large bending deformation by low voltage in broad fields such as medical engineering [2][3] . Moreover, researches using IPMC as a sensor have been done 4 , but there is a fault that IPMC operates only in water. Therefore, a solid polymer electrolyte (SPE) has been expected as a functional polymer which makes bending deformation by adding voltage like IPMC and can be used in air.…”

This paper describes a development of a curvature sensor using a solid polymer electrolyte (SPE) film. The sensor has a basic structure that an SPE film is sandwiched between thin carbon films. Each carbon is coated with Ag paste and they are covered with polymer films. The SPE film has good flexibility, and can be used in air. In previous research, we clarified output response to deformation of the SPE sensor and the relationship between sensor output and sensor curvature. In this paper, in order to obtain the output characteristics of the curvature sensor, the influence of the position of partial deformation on the sensor output and the relationship between the sensor output and the area size of the deformed part in the SPE film were investigated. As a result, it is found that the sensor output is independent of the position where deformation is applied and that the sensor output has a proportional relation with the area size of the deformation part. Moreover these findings suggest that the sensor output is related to the average of the curvature of the measured surface.
