Micromechanical Silicon Gyroscopes

In financial terms micromechanical engineering is insignificant when compared to the multi-billion-dollar semiconductor industry; in technological terms, however, the progress being made in micromechanical sensors is enormous. Particularly commercially interesting examples of this are accelerometers and rotation sensors, also called gyroscopes. As manufacturing prices inexorably fall, so the number of applications rises.
