s With the advancements of MEMS foundry services and CAD tools, MEMS devices can be costeffectively designed and prototyped. Here, four designs that utilize these tools are presented: 1) a flexure design used to reduce the device warpage resulting from the mismatch in thermal expansion coefficients between the device and the substrate for flip-chip bonded MEMS, 2) a digitally positioned micro-m...

Microelectromechanical Systems (MEMS) is the technology of the very small, and merges at the nano-scale into "Nanoelectromechanical" Systems (NEMS) and Nanotechnology. MEMS are also referred to as micro machines, or Micro Systems Technology (MST). MEMS are separate and distinct from the hypothetical vision of Molecular nanotechnology or Molecular Electronics. MEMS generally range in size from a...
