Talk Title
Cost-efficient Triboelectric Nanogenerators for Powering and Sensing Purpose
Talk Abstract

Triboelectric nanogenerators (TENGs) are smart devices that are capable of harvesting the low-frequency energy and as sensors. Paper has attracted our attention as a low-cost, portable, and convenient flexible substrate. After a series of experiments we found paper serves excellently as both triboelectric pair and supporting part. We used paper and some cost- effective material to form a TENG, and we also design different structures to improve the performance of TENGs. These TENGs could harvest the mechanical energy generated by motion of the human body and can be used as sensors. On the other hand, waste material based TENG is another research direction, which not only reduce the waste of resources but can also mitigate environmental pollution and reduce energy consumption. We have chosen milk and waste tea leaves for in-depth research, and found the excellent performance of these two materials as a friction part. The study make a significant contribution toward the practical implementation of TENGs to green energy harvesting, office environmental monitoring, intelligent recognition, and robot skin applications.
