Abstract
A microelectromechanical system (MEMS) sensor assembly comprises a substrate, a bump stopper extending from the substrate, and a sensor suspended relative to the substrate. The sensor is configured to move relative to the substrate, wherein the bump stopper is configured to restrain the sensor travel distance and prevent contact between the sensor and the substrate. The bump stopper has a surface facing the sensor, wherein an area of contact between the sensor and the surface is less than the total area of the surface.
