Recent developments in functional triboelectric nanogenerators for flame-retardant, human health, and energy-harvesting fields: a crucial review

Abstract

In recent years, the rational use and development of energy has become an important research direction. As a novel technology, triboelectric nanogenerators (TENGs) can effectively convert other energy from around the environment into electricity. TENGs have wide applicability due to their adjustable structures, but they are still limited to a certain extent in some special fields. For example, some special requirements for triboelectric materials need to be addressed when a TENG is applied in a high temperature environment, in water, in wind, or for human health. Therefore, this review introduces some TENGs applied in special environments, and provides a reference for the preparation and application of functional TENGs. It provides a new idea for the preparation of multifunctional TENGs and their wide application in various fields.
