Quantifying Wetting Dynamics with Triboelectrification [PDF]
Advanced Science, 2022 Wetting is often perceived as an intrinsic surface property of materials, but determining its evolution is complicated by its complex dependence on roughness across the scales.

Does Flexoelectricity Drive Triboelectricity? [PDF]
Physical Review Letters, 2019 The triboelectric effect, charge transfer during sliding, is well established but the thermodynamic driver is not well understood. We hypothesize here that flexoelectric potential differences induced by inhomogeneous strains at nanoscale asperities drive

PET-PZT Dielectric Polarization: Electricity Harvested from Photon Energy [PDF]
MicromachinesThe effect of residual stress or heat on ferroelectrics used to convert photons into electricity was investigated. The data analysis reveals that when the PET-PZT piezoelectric transducer is UV-irradiated with a 405 nm wavelength, it becomes a photon ...

A Wireless Triboelectric Nanogenerator [PDF]
Advanced Energy Materials, 2017 AbstractA new “wireless” paradigm for harvesting mechanical energy via a 3D‐printed wireless triboelectric nanogenerator (W‐TENG) comprised of an ecofriendly graphene polylactic acid (gPLA) nanocomposite and Teflon is demonstrated. The W‐TENG generates very high output voltages >2 kV with a strong electric field that enables the wireless ...

The triboelectricity of the human body
Nano Energy, 2021 Abstract Triboelectrification (contact electrification) as a physical phenomenon appeared for the first time in a dialogue by Plato around 400 B.C. The phenomenon described in the dialogue is about amber that people wear attracting dry hair. The description also indicated that triboelectrification was first discovered on the human body.

Selection rules of triboelectric materials for direct-current triboelectric nanogenerator [PDF]
Nature Communications, 2021 AbstractThe rapid development of Internet of Things and artificial intelligence brings increasing attention on the harvesting of distributed energy by using triboelectric nanogenerator (TENG), especially the direct current TENG (DC-TENG). It is essential to select appropriate triboelectric materials for obtaining a high performance TENG.
