Outline of Final Research Achievements

The purpose of this study is a well fabrication of a sandwich structure of graphene/ZnO nano-rods/graphene. The layered structure can be expected to realize a high sensitive force sensor with flexibility. To accomplish the purpose, the optimal conditions for bringing up ZnO nanorods on graphene and the binding method graphene sheet on ZnO nanorods were incestigated.
As for the main results in this study, 1) morphological condition of graphene for direct growth of ZnO nanorods could be found out, 2) uniform growth of graphene could be obtained by optimization of substrate condition, 3) the sandwich structure could be fabricated by using conducting polymer PEDOT:PSS for binding of ZnO nanorods and graphene sheet.

Academic Significance and Societal Importance of the Research Achievements

本研究で、グラフェン／ZnOナノロッド／グラフェンのサンドイッチ構造を作ることができた。この構造体は、シリコンゴムなどの柔軟な材料で保持して、フレキシブルフォースセンサーにできる。ZnOナノロッドはフォースのみならず、ガスも検知できるので、人体や衣服に直接貼り付け、人体の動き、人体から発生する体臭・分泌液を検知できるフレキシブル多機能センサーへの応用が可能で、健康・福祉分野への貢献が見込まれる。
