Michigan Micro Mote (M3), the world’s smallest computer, is taking its place among other revolutionary accomplishments in the history of computing at the Computer History Museum in Mountain View, CA. Measuring in at less than a half a centimeter, it didn’t take a truck to transport the computers from their home in Ann Arbor, MI. In fact, nearly 150 of these computers fit inside a single thimble. The M3 is a fully autonomous computing system that acts as a smart sensing system. It is the achievement of Michigan faculty members David Blaauw, Dennis Sylvester, David Wentzloff, Prabal Dutta and several key graduate students over the years, some of whom have already founded companies to exploit key aspects of the technology. These devices are helping usher in the era of the Internet of Things (IoT), where people are connected to things and other people through the cloud.
