Conversion Electrode and Drive Capacitance for Connecting Microfluidic Devices and Triboelectric Nanogenerator

Abstract

Microfluidics is a technique that uses channels of tiny sizes to process small amounts of fluid, which can be used in biochemical detection, information technology, and other fields. In the process of microfluidic development, there are many problems that need to be solved urgently. Many microfluidic systems require the support of external devices, which increases the construction cost, and the electronic interface technology is not mature. A triboelectric nanogenerator (TENG) can harvest mechanical energy and turn it into electrical energy. It has been greatly developed now and is widely used in various fields. Nowadays, many studies are committed to the study of TENGs and microfluidic systems. The microfluidics device can be combined with a TENG to convert fluid mechanical signals into electrical signals for transmission. Meanwhile, TENGs can also act as a high-voltage source to drive microfluidic motion. In this paper, we reviewed the development of microfluidics and related technologies of microfluidic systems in conjunction with TENGs and discussed the form of electronic interface between microfluidic systems and TENG devices.
