Abstract
A haptic device with ultrasonic actuation, including: a support, a user-interaction element movable at least in rotation and/or translation relative to the support, a first contact surface that moves as one with the interaction element, a second contact surface that moves as one with the support, resonators, and a control unit that excites the resonators at at least one resonance frequency, generating a vibration mode in a plane and an ultrasonic lubrication phenomenon between the first contact surface and the second contact surface.
