“…(1) values ranging from 4 to 7 Å were obtained for the mean square displacement of the anions. These values are close to the diameter calculated for the imidazolium cations and the NTf 2 -anions, and very close to the values observed by Huber et al [30].…”

“…Unlike the studies on the change in the electrical properties of ionic gel depending on the type and contents of the ionic liquids, we will study the change in the ionic gel brought on by external mechanical forces. Regarding the internal changes in the ionic gel, when the sensor was stimulated by external loads, ILs trapped inside the TPU matrix of the ionic gel came out through the soft segment of the polymer matrix and moved like free ions.…”

through the discrimination of multiple mechanical stimuli. [3] Therefore, the ideal artificial electronic skin can discriminate external loads from various types of input and can also detect intensity.Furthermore, the electronic skin must have properties that satisfy corresponding requirements for tactile sensing. For example, there are several relevant para meters that electronic skin sensors must measure, such as sensitivity, working range, detection time, and hysteresis. The measurement of these is important in order to realize the tactile sensing of human activities or motions. To demon strate electronic skin with the capabili ties of humanskinlike tactile sensing, many researchers have studied novel materials with improved sensing perfor mance, including carbon nanotubes, [6][7][8][9][10][11][12] flexible elastomers, [3,4,6,[13][14][15][16][17] conducting polymers, [14,18,19] ionic gels, [5,7,[20][21][22][23] nanowires [24] or materials with the structure of nanoneedles, [25] hemispheres, [3,5,26,27] and pyramids. [10,14,[28][29][30][31] However, most of the previous studies have focused on the capability to perceive only a single type of mechanical stimulus, rendering previous attempts at designing an electronic skin incapable of sensing multiple forms of mechanical loads.Previous studies have reported sensors with different mate rials and structural approaches for the detection and discrimi nation of the perception of multiple mechanical stimuli. Yin et al. developed the fiber strain sensor for tensile, bending, and torsionsensitive properties using graphenebased composite fiber. [32] In the present study, a fiber strain sensor was fabri cated in a compression spring structure through a facile solu tion process with high reproducibility. Pang et al. presented an interlockingbased straingauge sensor for detecting multiple mechanical forces (including normal, tangential, and torsional forces) using Ptcoated microhair arrays. [33] This strain sensor allowed for a simple and robust sensing platform using the interlocking structure for largearea sensing. Despite the poten tial of devices such as these, the sensors presented in previous reports exhibited low sensitivity for the perception of external mechanical stimuli in a low sensing range with only small elec trical signal differences. They could also only detect a limited range of mechanical loadings.To improve the performance of tactile sensors, a new tac tile sensor should be designed by taking different approaches than the traditional approaches. In this study, we fabricated a tactile sensor composed of an ionic gel inspired by the ionic Sensors that detect and discriminate external mechanical forces are a principal component in the development of electronic tactile systems that can mimic the multifunctional properties of human skin. This study demonstrates a pyramid-plug structure for highly sensitive tactile sensors that enables them to detect pressure, shear force, and torsion. The device is composed of pyramidpatterned ionic gel inspired by neural mec...
