Chapter-4 (Introduction to FEM Analysis using COMSOL MULTIPHYSICS) 4.1 Introduction: In simplest form we can define Micro Electro Mechanical Systems (MEMS) as miniaturized electro-mechanical devices made by using various techniques of micro-fabrication, where the dimensions can be in the range from less than one micron to several millimeters. Many MEMS devices are of the size of a grain or the eye of a needle. MEMS is indeed one of the most promising and emerging areas of engineering. This…

Hmmm, I wonder if there is a way to create an ultrasound machine that could create 3D images. Kazunori Baba, M.D., Ph.D. thought to himself one day. For a time Kazunori Baba has been realizing the benefits of such a machine. He thinks to himself, the benefits of a 3D ultrasound would be monumental, my expecting mothers could not only see their babies in real time, but as a doctor I would also be able to better see the babies and find any possible birth defects before the delivery. But will there…
