Triboelectric Effect-Driven Liquid Metal Actuators

Soft Robotics, 2019
Owing to the perfect combination of metallic conductivity, liquid fluidity, and mechanical stability, liquid metals (LMs) are considered the potential materials of the electromechanical system and the basic components of liquid robot. Here, triboelectric effect-driven liquid metal actuators (TLMAs) have been demonstrated, in which the motions of LMs ...

Triboelectrical Effects in Frictional Contacts

Solid State Phenomena, 2006
In the paper results of investigations of triboelectrical effects, proceeding in nonlubricated contacts, observed as “friction microcurrents”, and also in lubricated contacts - as “generated potential difference” are presented. Analysis of change dynamics of “friction microcurrents” and “generated potential difference” is making it possible to direct ...

Flexoelectric effect driven colossal triboelectricity with multilayer graphene

Current Applied Physics, 2021
Abstract Converting mechanical deformation from surrounding environment into detectable electrical signals remains one of the most attractive fields due to its potential applications in sustainable energy harvesting, self-powered sensors, and others. Presently, deformation energy is harvested by generating voltage/current through bending/twisting of ...

Temperature Effect on Performance of Triboelectric Nanogenerator

Advanced Engineering Materials, 2017
The triboelectric nanogenerator (TENG) is a promising energy harvesting technology that can convert mechanical energy into electricity and can be used as self‐powered active sensors. However, previous studies are mostly carried out at room temperature without considering the temperature effect on the electrical performance of TENGs, which is critical ...

Hybrid Aerogel Triboelectric Nanogenerator Based on the Synergistic Effect of Solid–Solid/Gas–Solid Triboelectricity and Piezoelectric Polarization

ACS Applied Materials & Interfaces, 2023
Aerogels, due to their unique interconnected 3D networks, and large number of air-filled pores, extend the structural characteristics and physicochemical properties of the nanoscale to the macro level. However, aerogels made from a single component can hardly meet the needs of multifunctional energy harvesting/supply situations.

Size dependent triboelectric nanogenerator and effect of temperature

2018 3rd International Conference on Microwave and Photonics (ICMAP), 2018
A layered structure of triboelectric nanogenerator (TENG) has been fabricated in the contact separation mode with plain paper, highly dielectric (PTFE) polytetrafluoroethylene and conductive aluminium layers, respectively. The output responses were recorded in form of electrical voltage by the triggering of mechanical interactions over the TENGs ...

Triboelectric Effects in Rocks

1971
Electrostatic phenomena are quite varied and occur widely in nature. The development of an electrostatic charge from mechanical action on a solid body is termed a triboelectric effect. Such effects have not yet been well studied, though the question of various forms of electrification of different solid bodies has been the subject of considerable work [

Effect of Polymer Structure on its Triboelectric Properties

IEEE Transactions on Industry Applications, 1976
An experimental procedure is reported for the determination of the triboelectric charging of polymer films, which has sufficient precision to allow systematic observations of the variations of charge values which result from systematic changes of polymer structure (by copolymerization and with additives).
