摘要/Abstract

摘要：研究了由超声波驱动的直流纳米发电机的发电原理，该发电机是一个无序能量收集器，能把纳米尺度的无规则或无序的微小机械能转变成有秩序的电能，即该纳米发电机是一个能把混乱整理成秩序、能从无序中提炼出有序的装置.计算了随机振动噪声所引起的纳米发电机输出的直流电流大小，在一定的条件下，这种纳米发电机的输出电流大小可以达到240 nA且可以由实验来测量的.

关键词： 纳米发电机, 随机振动, 无序能量收集器

Abstract: The principle of the direct-current nano-generator driven by ultrasonic waves is studied.It is shown that the nanogenerator is a wonderful disorder-energy harvester,it can convert nanoscale random minor mechanical energy into electrical energy;in other words,it is a wonderful device that can convert mess into order and refine order from disorder.The direct-current value of the nano-generator caused by stochastic vibrations noise is also calculated.Under certain conditions,the direct-current value of the nanogenerator can achieve the level of 240 nA,which can be measured by experiment.

Key words: nano-generator, stochastic vibration, disorder-energy harvester
