自从手提电脑和手机等个人可移动电子产品普及以后,解决小范围的用电显得格外重要.我们目前主要靠的是蓄电池.在未来不久,由于微纳系统的发展以及它们在原位人体健康的实时监测、基础设施的监测、环境监测、物联网以及军事技术上的应用,传统的利用蓄电池来提供电源的方法将不能满足或不能适应传感器网络的工作环境和要求.在2005年,作者提出了自驱动的概念,其根本是利用从环境中收集的能量,通过能量转换来驱动这些微纳系统,实现功率自给.本文介绍作为微纳系统中可持续自供型电源的一种——纳米发电机的研究和未来应用.
Ever since the wide range applications of laptop computers and cell phones,seeking of power sources for driving portable electronics is becoming increasingly important.The current technology mainly relies on rechargeable batteries.But for the near future,micro/nano-systems will be widely used in health monitoring,infrastructure and environmental monitoring,internet of things and defense technologies;the traditional batteries may not meet or may not be the choice as power sources for the following reasons.To meet these technological challenges,the author proposed the self-powering nanotechnology in 2005,aiming at harvesting energy from the environment to power the micro/nano-systems based sensor network.This article is to introduce the nanogenerator as a sustainable self-sufficient power source for micro/nano-systems.
