Digging around for some information on MEMs gyroscope manufacturing processes, I came across this excellent white paper that explains a lot of the options that manufacturers have making low cost gyroscopes. MEMs is a really fascinating business to be in, with very real manufacturing challenges, but some very unique opportunities as well. Most of the driving force behind MEMs in recent years has been smart phones — by far the single biggest market for MEMs gyros! — but the DIY and HW world definitely benefits from this since it’s never been cheaper or easier to get high quality motion sensors. Curious how MEMs gyros are made? Have a look at: A Critical Review of the Market Status and Industry Challenges of Producing Consumer Grade MEMS Gyroscopes from Invensense.
