| Outline of Final Research Achievements |
In order to develop a flexible co-generator with a hybridization of thermoelectric (TE) and piezoelectric (PE) materials, we have investigated TE characteristics of flexible fabrics covered with ZnO-nanocrystals. As a result of doping Sb and Ag into ZnO-nanocrystal/fabrics, it was found that the Sb-ZnO nanocomposite has a Seebeck coefficient of n-type semiconductor while the Ag-ZnO nanocomposite shows a p-type semiconductor.
For an n-type Si wafer attached with a commercial PE device, its electromotive force was measured under a temperature gradient and a vibration of the PE device. The obtained characteristics suggested that the carrier injection and emission between the PE material and Si occur.

| Academic Significance and Societal Importance of the Research Achievements |
熱水法を用いてZnOナノ結晶の布材料表面への成長に成功したことは，低コストかつ大面積のフレキシブル熱電材料を生産できる見通しが得られたことを意味している．さらに同じ手法で作製したSb-ZnO混合ナノ結晶とAg-ZnO混合ナノ結晶素子が，それぞれn型とp型のフレキシブル熱電特性を示したことから，ウェアラブル発電素子の実用化の可能性が高まった．
また，フレキシブル材料の膜厚方向の熱電特性を評価する装置を構築したことは，今後のウェアラブル発電素子材料の開発に大きく貢献するものである．
