MEMS is also used for laser beam steering (depth sensors, projectors), oscillators and even loudspeakers. MEMS is truly a breakthrough where physics meet electronics.

Commercially MEMS is also very interesting because it’s a branch of semiconductor manufacturing which is dominated by different players compared to the regular TSMC/Samsung/Intel trifecta.

Some devices use MEMS oscillators instead of crystals, which has the bizarre side effect of making them allergic to helium: https://ifixit.org/blog/11986/iphones-are-allergic-to-helium...
