5、forself-powerednanosystems.摘要本文报告一个简单而有效的方法,可扩展的sweeping-printing-method命名,因为制作灵活(香港)nanogenerator血库,能有效地收获机械能量来驱动小型商业电子器件。该技术包括两个主要的步骤。在第一步的氧化锌奈米线垂直对齐(NWs)转移到一个接收基体形成横向对齐的数组。然后,平行条纹沉积类型的电极连接所有的新创建在一起。采用单层结构的香港,一个开路电压2.03V,输出功率密度峰值∼11mW/cm3已经达成。所产生的电力能源有效利用电容器存储,并成功用于照亮一个商业发光二极管,这是一个具有里程碑意义的进步对建立自我动
