Briefly, in accordance with one or more embodiments, a coil for a MEMS device, and/or a structure on which the coil is disposed, may have one or more linear segments and one or more non-linear segments. One or more of the non-linear segments may be curved to increase a responsiveness of the coil to the magnetic field in which the coil is operating to provide an increased torque on the rotation of the mirror of the MEMS device in response to a drive signal applied to the coil in the presence of the magnetic field. The non-linear coil may have other shapes and may be any arbitrary shape.
