Triboelectric Nanogenerator and Integration with Electrochemical Microsupercapacitor

With the rapid development of economy and society, microelectronic devices play a more and more important role in our daily life. An important challenge for electronic devices is that the energy storage device is not capable of providing reliable energy for the operation of the electronic device for a long time, resulting in frequent charging or battery replacement. In order to meet the need of the sustainable operation of the next generation electronic equipment, the development of the self-charging energy storage device based on the nanogenerator has made remarkable progress. This paper reviews the device design, working principle, self-charging performance and the potential application prospect of the self-charging memory device. In addition, the challenges facing the self-charging energy storage device are also discussed.
