研究了一种采用ZnO纳米棒和碳纳米结构的新型压电器件。虽然不能观察到明显的压电性，但可以成功地从具有半导体特性的高取向ZnO纳米棒中观察到压电电阻率。另一方面，利用溅射技术可以在衬底上制备定向碳纳米片。为了实现压电器件，需要在电极上插入纳米棒或碳纳米结构。本研究为纳米棒与导电聚合物的连接提供了新的途径。

Study on a new piezoelectric device using ZnO nanorods and carbon nanostructures was carried out. However a clear piezoelectricity could not be observed, piezo-resistivities could be successfully observed from highly oriented ZnO nanorods with semiconducting properties. On the other hand, oriented carbon nano-flakes could be prepared on substrates by sputtering technique. It is necessary to interpose nanorods or carbon nanostructures by electrodes to realize the piezoelectric devise. In this study, the new technique of jointing nanorods with conducting polymer could be developed.
