Abstract:
1. A micro-electro-mechanical-system (MEMS) device, comprising: a first rotational actuator having a first rotation axis; a second rotational actuator having a second rotation axis, wherein the first and second rotation axes are non-parallel; a device mount; a first bi-axial linkage coupled between the device mount and the first rotational actuator without an intervening frame, wherein the first biaxial linkage includes a first flexure beam configured to flex about a first flexure axis and a second flexure beam configured to flex about a second flexure axis that is non-parallel to the first flexure axis; and a second bi-axial linkage coupled between the device mount and the second rotational actuator without an intervening frame, wherein the second biaxial linkage includes a third flexure beam configured to flex about a third flexure axis and a fourth flexure beam configured to flex about a fourth flexure axis that is non-parallel to the third flexure axis, wherein the first and second bi-axial linkages provide the device mount with two or more degrees of freedom of movement, wherein the first and second bi-axial linkages and device mount are formed from the same device layer.
