The triboelectric effect (TE), simply described as the generation of electricity from tribology or friction, has been known for over 1500 years. TE arises charge transfer between surfaces under contact, typically attributed to electron transfer. However, emerging understanding shows how ion and material (bond cleavage) mechanisms play a key role in TE. An engineering focus on increasing porosit...

Friction between dielectric surfaces produces patterns of fixed, stable electric charges that in turn contribute electrostatic components to surface interactions between the contacting solids. The literature presents a wealth of information on the electronic contributions to friction in metals and semiconductors but the effect of triboelectricity on friction coefficients of dielectrics is as ye...

With respect to the theory of four Triboelectric Generators (TEGs) operational modes, a testing method is proposed. It describes and imitates more precisely real conditions motion materials in wearable clothing based TEG. The phenomenon triboelectricity investigated from clearly textile approach, using typical fabrics made by ordinary production methods environmental friendly materials. perform...

Triboelectric generator is attracting much attention as a power source of electronics application. Electromotive force induced by rubbing key for triboelectric generator. From dielectric physics point view, there are two microscopic origins electromotive force, i.e., electronic charge displacement and dipolar rotation. A new way evaluating these an urgent task. We have been developing optical s...
