Micro scanning mirror

A micro scanning mirror, comprising a lens, a piezoelectric material layer, two first rotating shaft elements, and a plurality of first driving electrodes, wherein

• a first axial direction passes through a center of the lens,
• the piezoelectric material layer is arranged along a circumferential direction of the lens, wherein the piezoelectric material layer has a plurality of first driving electrode regions, and two first spacing regions where the piezoelectric material layer is not disposed are respectively formed between two adjacent first driving electrode regions of the plurality of first driving electrode regions,
• the two first rotating shaft elements are respectively located on two opposite sides of the lens along the first axial direction, and each of the two first rotating shaft elements is located between one of the two first spacing regions and the corresponding two adjacent first driving electrode regions, wherein each of the two first rotating shaft elements connects the lens and the piezoelectric material layer located in the corresponding two adjacent first driving electrode regions,
• the plurality of first driving electrodes are respectively located on corresponding first driving electrode regions of the plurality of first driving electrode regions, and the piezoelectric material layer is respectively driven by corresponding first driving electrodes of the plurality of first driving electrodes, so that the two first rotating shaft elements drive the lens to rotate around the first axial direction after the piezoelectric material layer located on both sides of each of the two first spacing regions is deformed.
