The Determination of the Location of Contact Electrification-Induced Discharge Events

Introduction

Contact electrification - the transfer of charges from one object to another when brought into contact and separated - is ubiquitous and has been known for a very long time. Yet, there are still fundamental questions that are not fully understood, such as the role of friction in the transfer of charges. Contact electrification is associated with friction, and yet it is not known if friction is the mechanism for contact electrification or merely incidental to the pressures required to bring the two surfaces together. The authors reported a system of a steel sphere rolling in a circular path on an organic insulator. As the steel sphere
