Sandia MEMS Videos

[@TheExplosiveGuy]

Fascinating stuff, I've always loved MEMS tech. Interesting little blips of audio lol.

Is the periodic brightening and darkening of the combs at 1:01 because the voltage on them interacts with the electron microscope image?

[@N.M.E.]

Yes! The combs are electrically charged so they attract and repulse. That's what makes them move, and also "glow" (in the case of negative charge) under the SEM!

[@francischan8263]

how did they even manufacture those gears and shafts in that scale?

[@sickleandsuckle]

This is a great visualization.

Some of the segments seem to have problems with the video compression (pixellation comes and goes in time with the motion depicted)

[@DennisAdams]

These are videos created by Sandia National Labs in the early 2000s, so they are likely a decade and a half old. At the resolution used and the scale of the MEMS, it's remarkable a clear video was captured.

@@DennisAdams Yes, indeed, but I'm talking not about poor resolution but rather what appears to be an encoding error - several of the snippets have white blocks which appear and disappear constantly during the snippet, which is usually indicative of video compression artifacts due to corrupted data (similar to what happens in digital broadcast TV when the signal is momentarily lost). The original video from Sandia would not have such artifacts.

@@DennisAdams The first instance of what I'm talking about is at 1:24
