Abstract
A button device includes a fixed support structure; a movable structure, laterally surrounded by the support structure and configured to deform at least in part under the action of an external force; and a fluid-tight protection cap. The movable structure includes a piston element, deformable elements having piezoelectric transducers arranged thereon, and anchor elements that couple the piston element to the deformable elements. When an external force acts on the piston element, the anchor elements transfer this force to the deformable elements and to the piezoelectric transducers, so as to sense the extent of this force.
