    Abstract: A microelectromechanical systems (MEMS) scanning device comprising a torsional beam flexure that has a variable width in relation to a rotational axis for a scanning mirror. The geometric properties of the torsional beam vary along the rotational axis to increase a desired mode of mechanical strain at a location where a strain sensor is operating within the MEMS scanning device to generate a feedback signal. The torsional beam flexure mechanically suspends the scanning mirror from a frame structure. During operation of the MEMS scanning device, actuators induce torsional deformation into the torsional beam flexure to cause rotation of the scanning mirror about the rotational axis. The degree or amount of this torsional deformation is directly related to the angular position of the scanning mirror and, therefore, the desired mode of mechanical strain may be this torsional deformation strain component.
