The mainstream friction mechanism under the influence of an external electric field (IMAGE)
Caption
The electric field can be regarded as a "multifunctional stimulus source", which can dynamically regulate interface charges, lattice configurations, chemical states and vibration dynamics through five core physical mechanisms: electrostatic effect, electrostriction, electron-phonon coupling, electric field-induced redox, and mechanical resonance. Thus, it can precisely alter the energy dissipation path and achieve active and reversible control of the friction coefficient.
