Triboelectric Nanogenerators Enable Multifunctional Ice Accretion, Melting, and Interfacial Fracture Detection.

ABSTRACT: Triboelectric nanogenerators (TENGs) have significant potential to perform as sensors or compact electric power generators through the production of electrical charge during the frictional interactions between two dissimilar materials, such as liquids impacting solids. However, whether phase transitions generate a triboelectric response is not known. This study investigates the occurrence of triboelectrification during the water-ice phase transition using TENGs for real-time ice detection on critical engineering surfaces such as aircraft, wind turbine blades, and vehicles. TENGs are fabricated using aluminum electrodes and either polyethylene, silicone, or polytetrafluoroethylene as the dielectric. The freezing of water and the melting of ice are found to generate triboelectric current onl
