Abstract (en)
[origin: WO2021152227A1] The invention relates to a touch interface comprising, on the one hand, an interfacial surface able to generate a haptic-feedback effect in response to a touch of said surface by a user, and, on the other hand, at least one piezoelectric actuator (2, 3) configured to generate, in said interfacial surface, at least one wave of ultrasonic frequency able to endow the particles of this surface with an elliptical movement having a movement component tangential to said surface, which component is denoted ut(t), and a movement component normal to said surface, which component is denoted un(t), characterised in that said wave of ultrasonic frequency is chosen so that the amplitude Ut of the tangential component ut(t) and the amplitude Un of the normal component un(t) are substantially equal.
