| Outline of Final Research Achievements |
The aim of this project is to develop an artificial optical smart skin mimicking the principle of display systems of biological skins observed in nature. Firstly, we developed a pigment-based display device using electroactive PAMPS hydrogel. We fabricated 3 x 3 dot matrix display by combining PAMPS sheets and a wiring substrate, and succeeded in switching the display by using deformation of the PAMPS sheets. Secondly, to fabricate a display device based on structural color, we developed a "Channel-Cut Method" to pattern multiple types of photonic colloidal crystals into a PDMS sheet. We succeeded in fabricating a optical filter with patterned two different color dots and confirmed that the specific wavelength reflected by the patterned photonic crystals matches well to theoretical prediction.
