Tactile perception by friction induced vibrations [PDF]
Tribology International, 2011 When a finger moves to scan the surface of an object (haptic sensing), the sliding contact generates vibrations that propagate in the finger skin activating the receptors (mechanoreceptors) located in the skin, allowing the brain to identify objects and perceive information about their properties.

A New Efficient Adaptive Control of Torsional Vibrations Induced by Switched Nonlinear Disturbances
International Journal of Applied Mathematics and Computer Science, 2019 Torsional vibrations induced in drilling systems are detrimental to the condition of the machine and to the effectiveness of the engineering process. The cause of vibrations is a nonlinear and unknown friction between a drill string and the environment ...

Acoustic Energy Transfer by Friction Induced Vibrations
Procedia Engineering, 2017 Abstract Friction-induced vibrations are often investigated for their unwanted effects, such as surface wear and dynamic instabilities. This article focuses on the exploitation of friction-induced vibrations to transfer the energy between different acoustic fields by an interface under frictional contact.
