Silicon-based MEMS techniques are useful for sub-millimeter applications. While conventional methods exist to produce larger machines measured in centimeters and beyond, the so-called mesoscale devices remain difficult to manufacture. This video shows a versatile and radically simple fabrication process, loosely based on printed circuit board manufacturing techniques, for creating a topologically complex, three-dimensional machine. In this video, the technology is used to create a tiny bee thats the size of a quarter.
