Microelectromechanical systems (MEMS) combine tiny mechanical parts, electrical devices, and electronic circuitry using integrated-circuit (IC) fabrication technologies. The structural features in these systems are quite small (ranging from 1 to 100 microns), with a typical MEMS chip varying from 1 to 5 millimeters. These devices vary from simple spring-and-weight mechanisms to complex systems with multiple […]
What do drug discovery and delivery, the fight against COVID-19, and personalized “organs” all have in common? They need to move—and then analyze—tiny amounts of precious sample. While that sounds like a daunting task, dramatic progress in these fields (and many others) is being driven by the power of the small. The very small.
