Gels with Wave-Shaped Surfaces

Fig. 6.4. Mold for making gels with wave-shaped surfaces...

The combination of mold and obtained gels are shown from Figure 6.7 to 6.10. Thickness distributed gels and its mold are shown in Figure 6.7 and 6.8. Gels with wave-shaped surfaces and its mold are shown in Figure 6.9 and 6.10. 

Conjecture 2. If we make the gel with wave-shaped surface, it will deform along the ditch. 

Fixed-Ended Gel with Wave-Shaped Surfaces... 

Different from gel (a), gel (b) bent along the ditches. The gel (c) bent along y-axis, the same direction of the ditch on extending surface. The gel (d) also bent along y-axis, but the difference of two curvatures of each direction was larger than that of gel(c). In this way, the ideas were checked, of shape design improved controllability (Conjecture 1), and the gel with wave-shaped surface bend along... 

From the experimental results of gels with wave-shaped surfaces, it was compared that deformation response of gels with different width. Narrow gel should be possible to approximate as two-dimensional mechanism. In contrast, it should be difficult to ignore the stiffness change, which occurs by deformation along width direction for wide gel. 

Combination of gel with wave-shaped surfaces and matrix of multiple electrodes ... 

For the purpose of confirming these hypotheses, it was compared that simulation and experimental results of deformation response among the gel with smooth surface, the one with wave-shaped surface on only one side, or both sides. 

With this system, experiments were performed in three steps. First, it was simulated that the deformation of beam-shaped gel (bl) with wave-shaped on the face side and plane surface on the reverse side. A uniform electric field was applied to them by pairs of electrodes. The voltage between a pair of electrodes is 10[V]. The period for applying the electric field is 20[s]. Two cases were examined. In...
