| Outline of Final Research Achievements |
We proposed thermal conductivity measurement device which can measured nano, micro scale materials by extending 3-omega method. Specifically, we fabricated metal micro wire on an elastomeric ultra-thin film (nanosheet) with the thickness of several hundred nanometers by using photolithography. We confirmed that the electrical resistivity of metal micro wire formed on the elastomeric nanosheet was not changed even if the nanosheet was peeled off from a supporting layer, resulting in a free-standing state. The result showed that fabricated device can measure thermal conductivity by attaching measurement sample.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により実現した貼付型熱伝導率計測デバイスによれば、これまで測定が困難であった有機薄膜等の熱伝導率を簡便に計測・評価できる。この計測・評価は、薄膜の厚さ方向のみならず、面内方向に対しても可能であり、高い汎用性と実用性を有している。さらに、本デバイスを用いれば、これまではほぼ不可能であった非破壊での熱伝導率計測も可能であり、生体材料のその場計測など、幅広い応用が期待できる。
