  The gap is so small that a bacteria could easily fit between them. My garage is so small that a bacteria could easily fit inside.

  A few things about MEMS devices I have not been able to figure out is: 1. Is the sensing/moving structure actually disconnected from the rest of the device? 2. If so, how does it not get stuck to a side? 3. If it isn't disconnected, doesn't the friction from the connection cause an offset in the reading? 4. How do they etch the structure so that it is disconnected from the layer below?

    It would explain why every smart phone I have ever owned has gotten stuck in landscape until I shook it hard enough.

  Thanks! I didn't watch the video yet but their YT channel rocks. Subscribed. :D

  It's cool'cause there's a commercial baked into the middle of it.

  this is wild i literally did not realize we had them so small at this point

  I don't have time to watch the video but I was curious why MEMS gyros were shaped thus. Apparently it is to maximize sensitivity through the Coriolis force.

  Their peculiar geometry reminds me of computer-designed antenna.

  "How" Gyroscopes Got So Small.

  God, I so hate the auto-title "fixing" feature on HN.
