New Techniques for Building Microelectromechanical Systems

Researchers from MIT have developed new techniques for building microelectromechanical systems at one-hundredth of the current cost. Microelectromechanical systems — or MEMS — were a $12 billion business in 2014. But that market is dominated by just a handful of devices, such as the accelerometers that reorient the screens of most smartphones. That’s because manufacturing […]
