The Charging Events in Contact-Separation Electrification [PDF]
Scientific Reports, 2018 AbstractContact electrification (CE)—charging of surfaces that are contacted and separated, is a common phenomenon, however it is not completely understood yet. Recent studies using surface imaging techniques and chemical analysis revealed a ‘spatial’ bipolar distribution of charges at the nano dimension, which made a paradigm shift in the field ...

Electric Field and Humidity Trigger Contact Electrification
Physical Review X, 2015 Here, we study the old problem of why identical insulators can charge one another on contact. We perform several experiments showing that, if driven by a preexisting electric field, charge is transferred between contacting insulators.
