Triboelectric Nanogenerators as Power Sources

and Sensors for Flexible and Wearable Electronics

Abstract

Developing wireless nanodevices and nanosystems is of critical importance for sensing, medical science, environmental/infrastructure monitoring, defense technology and even personal electronics. It is highly desirable for wireless devices to be self-powered without using battery. Nanogenerators have been developed based on piezoelectric, trioboelectric and pyroelectric effects, aiming at building self-sufficient power sources for mico/nano-systems. Triboelectrification is a universal phenomenon that exists for all of the materials regarding their chemical structure and physical shape. This presentation will focus on the triboelectric nanogenreator based technologies for flexible and wearable electronics.
