A Bunch of Micromachines
Microfabrica's EFAB system was the first MEMS foundry process to accept CAD files as input, turning customer designs into micromachines much faster than traditional methods. EFAB builds the devices one metal layer at a time. In this image, the square at the top is a microfluidics device with internal passageways used for a "lab on a chip." The multi-arm device (center) is a fuel injection nozzle. Bottom left is an accelerometer (C-shaped wings), and bottom right is an inductor used in RF circuits. (Image courtesy of Microfabrica Inc.)
