| Outline of Final Research Achievements |
This research has been made to develop an artificial skin to cover future humanoid body. In order to realize such a multi-modal sensitive function on the artificial smart materials, hetero-core sensing techniques are successfully introduced in terms of sensing capabilities such as physical strains, tactile, vibration, liquid adhesion and humidity. These physical quantities has been detected in the form of a honeycomb panel. A artificial finger made of silicone rubber has been developed to show percpetion in the orders of micro epsilon in strain, micro meter of surface roughness, 10-2 dB/G of acceleration, together with liquid monitoring.

| Academic Significance and Societal Importance of the Research Achievements |
ヘテロコア技術は、従来の光ファイバセンサに比べ温度依存性がほとんどなく耐電磁誘導性や耐腐食性にも優れている上に、光強度ベースの計測方式を確立しているため、高いロバスト性とコスト効率をもった光学センサといえる。これらのセンサ機能を備えた光ファイバを知的構造体に実装することができれば、環境に左右されることなく、あたかも人間の神経のように様々な感覚を構造体に与える「光ファイバ式感覚神経」が実現できる。これにより、汎用性の高いマルチモーダルな感性を備えた人工皮膚による次世代ヒューマノイドロボットや人工義肢の高機能化が期待できる。
