==MEMS MIRROR DEVICE WITH PIEZOELECTRIC ACTUATION AND MANUFACTURING PROCESS THEREOF - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240019688 titled 'MEMS MIRROR DEVICE WITH PIEZOELECTRIC ACTUATION AND MANUFACTURING PROCESS THEREOF

==Simplified Explanation==

The abstract describes a micro-electro-mechanical mirror device that includes a fixed structure, a tiltable structure, a reflecting surface, and an actuation structure. The actuation structure is formed by a pair of actuation arms that cause rotation of the tiltable structure. The actuation arms are elastically coupled to the tiltable structure through elastic coupling elements. The bearing structure of each actuation arm is formed by a soft region of a first material, while the elastic coupling elements are formed by a bearing layer of a second material with greater stiffness.

==Original Abstract Submitted==

disclosed herein is a micro-electro-mechanical mirror device having a fixed structure defining an external frame delimiting a cavity, a tiltable structure extending into the cavity, a reflecting surface carried by the tiltable structure and having a main extension in a horizontal plane, and an actuation structure coupled between the tiltable structure and the fixed structure. the actuation structure is formed by a first pair of actuation arms causing rotation of the tiltable structure around a first axis parallel to the horizontal plane. the actuation arms are elastically coupled to the tiltable structure through elastic coupling elements and are each formed by a bearing structure and a piezoelectric structure. the bearing structure of each actuation arm is formed by a soft region of a first material and the elastic coupling elements are formed by a bearing layer of a second material, the second material having greater stiffness than the first material.
