Renewable energy systems using light, thermal, and mechanical sources have been developed to meet these needs. Among these, mechanical energy scavengers utilizing piezoelectricity have attracted great attention because they are suitable for a variety of applications ranging from electronic systems to molecular sensors. Intensive studies regarding piezoelectric/triboelectric flexible nanogenerators based on 1D/2D nanomaterials have been explored, demonstrating new implications such as fiber-type energy scavengers, piezotronic strain sensors, light-emitting diodes, and Schottky contact-based nano/biosensors in a self-powered mode. This talk will introduce the importance of nanogenerators as well as the recent advances in power generation through piezoelectric/triboelectric nanogenerators with the power generation mechanism. I will discuss recent research and design efforts that enhanced the power generation to commercialize the nanogenerators to power portable and wearable devices. |
