Peanuts vs. Pyramids: Two Perspectives on MEMS
Online Presentations | 29 Dec 2009 | Contributor(s):: Stephen D. Senturia
MEMS, the acronym for Micro-electromechanical Systems, also known simply as “Micro-systems,” come in two main types: commodity products (the peanuts) and MEMS-enabled products (the pyramids, or, more correctly, the inverted pyramids). The economics of scale greatly affect how these two classes of...
