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.

I was going to share this with my kid, but then the video turned into an advertisement for "war thunder" a free videogame.. no thanks

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'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

"How" Gyroscopes Got So Small.

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

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.

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