Abstract: A micro-electro-mechanical system (MEMS) device may comprise a first layer that includes a stator comb actuator; a second layer that includes a rotor comb actuator; a mirror structure that includes a mirror; and a first set of hinges and a second set of hinges configured to tilt the mirror structure about a first axis of the MEMS device based on a driving torque caused by the stator comb actuator engaging with the rotor comb actuator. The first set of hinges may be configured to resist a lateral linear force on the mirror structure in a direction associated with the first axis caused by the stator comb actuator engaging with the rotor comb actuator. The second set of hinges may be configured to resist an in-plane torque on the mirror structure about a second axis of the MEMS device caused by the stator comb actuator engaging with the rotor comb actuator.
