Abstract

We demonstrated coloring elements with high ratio change of the coloring area by using bending deformation of electroactive hydrogel. By using the nondimensional deflection α of a gel, we showed that the response time for the color change and the thickness of the coloring element can be designed. We fabricated a 3 × 3 dot-matrix display with α of 0.56 and evaluated the performance of the coloring element. As a result, the coloring area ratios in blank state and colored state were 7.6±4.6% and 92.1±4.6%, respectively. The response times were 12 seconds from blank state to colored state, and 13 seconds from colored state to blank state.
