A Single-Electrode Based Triboelectric Nanogenerator as Self-Powered Tracking System

摘要

The emerging nanotechnologies to harvest mechanical energy for building self-powered systems have attracted increasing attention in the past decade due to a vast increase in the number of portable electronics.) Currently, there are two typical physics effects being popularly used to fabricate nanogen-erators to convert small-scale mechanical energy into electricity. Piezoelectric nanogenerators rely on piezoelectricity as driven by random mechanical motion. Based on the coupling between triboelectrification and electrostatic induction, triboelectric nanogenerators (TENGs) have recently been utilized to harvest mechanical energy from irregular vibrations, triggering, sliding and rotations.' As a basic structure of all, two metal electrodes are mandatory in order for them to function, which may limit their applications in some cases and increase fabrication cost.
