摘要:

伴隨著經(jīng)濟(jì)和社會(huì)的進(jìn)步，人們對(duì)智能化、微型化、便攜式電子設(shè)備的需求越來越迫切，推動(dòng)了智能可穿戴器件和微電子系統(tǒng)的發(fā)展。供電系統(tǒng)是現(xiàn)代電子設(shè)備重要的組成部分，傳統(tǒng)電池存在續(xù)航短、污染重等缺點(diǎn)。因此，亟待尋求一種綠色可持續(xù)供電的微電子器件。相比于傳統(tǒng)納米發(fā)電機(jī)，柔性納米發(fā)電機(jī)以其優(yōu)異的柔韌性、機(jī)械性和易加工性成為當(dāng)前的研究熱點(diǎn)，為解決目前可穿戴電子設(shè)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(fā)電機(jī)近年來受到廣泛的應(yīng)用和關(guān)注。綜述了壓電式、摩擦電式和復(fù)合式納米發(fā)電機(jī)的國內(nèi)外研究進(jìn)展和工作原理，闡述了基于不同材料、結(jié)構(gòu)和應(yīng)用領(lǐng)域的納米發(fā)電機(jī)，并對(duì)其在復(fù)合器件中的應(yīng)用進(jìn)行了概述，對(duì)該領(lǐng)域的發(fā)展趨勢(shì)進(jìn)行了總結(jié)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.
