Triboelectrification of wood with PTFE

Journal of Electrostatics, 2013
Abstract Triboelectrification for a rolling contact between hardwood and softwood spheres and a polytetrafluoroethylene (PTFE) plane is studied. For a variety of experimental parameters, the saturation charge developed on the spheres was measured. The results are compared with those reported previously where PTFE spheres were rolled on wood planes ...

Water-Triboelectrification-Complemented Moisture Electric Generator

ACS Nano
Energy harvesting from ubiquitous natural water vapor based on moisture electric generator (MEG) technology holds great potential to power portable electronics, the Internet of Things, and wireless transmission. However, most devices still encounter challenges of low output, and a single MEG complemented with another form of energy harvesting for ...

Triboelectrification of materials used in tape heads

Journal of Electrostatics, 2006
Triboelectrification of tapes by read/write heads can result in either increased error rates or permanent damage to the heads through electrostatic discharge (ESD) or electrochemical processes. In order to understand these phenomena, we have studied triboelectrification between tapes and different tape head materials used in magnetic tape storage ...

Triboelectrification between polycrystalline and monocrystalline ice

Journal of Electrostatics, 2001
Abstract The triboelectrification of ice was measured using polycrystalline and monocrystalline ice samples. The resulting electrification could not be explained using the temperature gradient theory; instead, the following results were found: (1) The polycrystalline sample was always charged positively when put in contact with the monocrystalline ...

Triboelectrification‐Enabled Self‐Charging Lithium‐Ion Batteries

Advanced Energy Materials, 2017
AbstractLi‐ion batteries as energy storage devices need to be periodically charged for sustainably powering electronic devices owing to their limited capacities. Here, the feasibility of utilizing Li‐ion batteries as both the energy storage and scavenging units is demonstrated.

Triboelectrification and Razorbacks: Geophysical Patterns Produced in Dry Grains

Physical Review Letters, 2006
Electrostatic interactions between particles can dramatically affect granular flows, creating industrial safety and handling problems [K. N. Palmer, (Chapman and Hall, London, 1973), pp. 388-389]. We present experimental data demonstrating that charging of grains can also cause spontaneous self-assembly that may generate lasting geological patterns ...

Microscale gap breakdown induced by toner triboelectrification

Advanced Powder Technology, 2015
Abstract Microscale gap discharge-relaxation around toner particles during triboelectrification was investigated. Single toner layers of their thickness 10–20 μm were pinched and rubbed by two flat stainless steel electrodes between which various voltage differences were added.

Nanoscale Modulation of Friction and Triboelectrification via Surface Nanotexturing

Nano Letters, 2019
Nanoscale contact electrification (CE) of elastomer surfaces and the resulting tribocharge formation are important in many branches of nanotechnology but their mechanism is not fully clarified. In this Letter, we investigate the mechanism using the recently discovered phenomenon of replica molding-induced nanoscale CE.
