Abstract
A touch-sensitive interface has a contact surface that is able to be touched by an effector (e.g., a finger). The interface includes actuating transducers (e.g., piezoelectric transducers) allowing a standing flexural wave to be formed, in a resonant mode, extending over the length of the slab. The interface includes a detector for measuring the amplitude of the wave, and a detecting circuit for determining an attenuation signal, when the contact surface is touched by an effector. It includes a processing circuit for estimating a magnitude of the force exerted by the effector on the contact surface.
