Outline of Research at the Start

硬さと柔らかさの両方を兼ね備え、状況に応じて硬軟が変化する材料は、人間共存型ロボットをはじめとして様々な応用が期待される。この候補材料として、磁性粒子が分散したコロイドの可能性を調べる。提案者らの先行研究では、この材料は磁場を印加すると固化する性質を有する。本研究では、磁性粒子の様々な性質に着目して、これらの性質と「硬さ」、「柔らかさ」との関係を明らかにするとともに、人が感じる硬軟をプログラムできる材料の創製を目指す。

Outline of Final Research Achievements

For the development of human-friendly robots, smart materials that combine both hardness and softness, and whose hardness and softness change isothermally and reversibly depending on the situation, are required. As a candidate material, we have studied on the development of a concentrated colloid with polyhedral magnetic particles. Under no magnetic field, the magnetic colloids showed fluidity and exhibited "softness”. On the other hand, when a magnetic field was applied, the magnetic colloid to solidified. The "hardness" of the magnetic colloid depended on the particle concentration, the polyhedral shape of the particles, and the magnetic field strength. The magnetic colloidal material showed the possibility to be programmed to be hard or soft as perceived by humans.

Academic Significance and Societal Importance of the Research Achievements

硬さと柔らかさの両方を兼ね備え、状況に応じて硬軟が変化する材料は、人間共存型ロボットをはじめとして様々な応用が期待される。この候補材料として、磁性粒子が分散したコロイドの可能性を調べた。申請者らの先行研究では、この材料は磁場を印加すると固化する性質を有する。本研究では、磁性コロイド中の磁性粒子の様々な性質に着目して、これらの性質と「硬さ」、「柔らかさ」との関係を明らかにするとともに、人が感じる硬軟をプログラムできる視点から評価した。
