摘要:

伴隨著經濟和社會的進步，人們對智能化、微型化、便攜式電子設備的需求越來越迫切，推動了智能可穿戴器件和微電子系統的發展。供電系統是現代電子設備重要的組成部分，傳統電池存在續航短、污染重等缺點。因此，亟待尋求一種綠色可持續供電的微電子器件。相比于傳統納米發電機，柔性納米發電機以其優異的柔韌性、機械性和易加工性成為當前的研究熱點，為解決目前可穿戴電子設備的供電需求問題提供了重要方法和路徑。其中，柔性壓電式、摩擦電式等自供電模式納米發電機近年來受到廣泛的應用和關注。綜述了壓電式、摩擦電式和復合式納米發電機的國內外研究進展和工作原理，闡述了基于不同材料、結構和應用領域的納米發電機，并對其在復合器件中的應用進行了概述，對該領域的發展趨勢進行了總結和展望。

Abstract:

With the economic and social progress, people‘s demands for intelligent, miniaturized and portable electronic devices are more and more urgent, which have promoted the development of smart wearable devices and microelectronic systems. The power supply system is an important part of modern electronic equipment. Traditional batteries have shortcomings such as short battery life and heavy pollution. Therefore, it is urgent to find a green sustainable power supply for microelectronic devices. Compared with traditional nanogenerators, flexible nanogenerators have become current research hot spots due to their excellent flexibility, mechanical properties and processability, providing an important method and path for solving the current power supply requirements of wearable electronic devices. Among them, the self-powered mode nanogenerators of flexible piezoelectric and triboelectric have received widespread applications and attention in recent years. In this article, the research progress and working principles of piezoelectric, triboelectric and hybrid nanogenerators at home and abroad are reviewed, nanogenerators based on different materials, structures and application fields are expounded, and their applications in composite devices are summarized. The development trend of this field is summarized and prospected.
