Abstract

A microelectromechanical (MEM) device with an expanded PTFE material over the gap between movable structures to provide electrical connection across the gap and prevent particles from contaminating the gap. A microelectromechanical (MEM) device is also immobilized by placing an expanded PTFE material over the gap between movable structures. The expanded PTFE material can be made stiff during manufacture and then flexible after the manufacturing process is complete. An embodiment of the invention is a MEM device configured as a micro-actuator for a dual-actuator hard disk drive.
