Outline of Final Research Achievements

As a purpose of developing a non-contact linear motion actuator by optical stimulation, we have attempted to create a drive system that improved the efficiency of absorbing light and bundles flexible fibers to enable high-speed and uniaxial displacement.
We have selected a monomer having a photochromic molecular structure, prepared an environment for synthesizing a polymer material containing a photochromic molecule, and made it possible to adjust the material. On the other hand, a device have been prepared for irradiating a UV light on a microscope so that measurement could be performed while observing dynamically on a microscope, and it became a system for observing the driving phenomenon of a light-driven actuator in real time.

Academic Significance and Societal Importance of the Research Achievements

光運動材料を用いた非接触アクチュエータは、バルク組織構造を呈している為、大きな変形を誘導する事が物理的に困難である。ゆえに、大きなストロークを得る為には、柔軟かつ均等に光刺激を受けて変形する必要がある。上記課題を解決する事した報告は無く、高柔軟性を有するナノ線維構造の加工およびアクチュエータとしてのシステム構築を行う必要がある。この開発により、世界初の光駆動直動アクチュエータを実現する。
