Nanoelectromechanical systems

So here's some different techniques used.

MEMS, M-E-M-S, that means microelectromechanical system, but sometimes it might be nano, so it might be NEMS with an N. Here's MEMS versus microelectronics.

Indeed, yes, indeed.

Here's a history of MEMS back in 1939 with the PN junction, which is exactly what we're talking about just momentarily ago, a m- moment ago.
