The Trends editors have been tracking the evolution of MEMS technology for nearly two decades. In that time, these tiny systems have become dramatically smaller and more capable. As a result, they are on the verge of exploding into a wide range of game-changing applications. The industries affected will range from health care to counter-terrorism to cell phones to food preparation. What are the implications? What will this technology mean for your quality of life, your career, and your investments? We’ll show you.
