Haptics and Electrovibration

Due to the growing interest in robotic and haptic applications, voltage-induced friction has rapidly grown in importance in recent years. We present a new macroscopic model for voltage-induced frictional contacts, which stands out due to a suitable coupling between contact mechanics and electrostatics. Therefore, we exploit the close analogy to classical adhesion theories and recalculate the adhesion force per unit area as well as the effective surface energy.


As an application, we consider the frictional contact between the fingertip and touchscreen under electrovibration.  View this paper:  https://www.mdpi.com/2075-4442/7/12/102
