I have performed a few experiments with a vibrating bracelet. It is connected to a phone by Bluetooth, and when the bluetooth link is severed, the bracelet starts to vibrate, indicating theft.
I asked my phone to turn off bluetooth for a few seconds, then turn it back on, producing a series of 1 second on, one second off vibrations.
So far, the results have been inconclusive. Maybe I need a lot more attempts per night to see if that works.

Or maybe a response to a stimulus wouldn't occur in deep sleep, but would in REM sleep.
There are measurements of EOG (electro oculogram) and EMG (electro myogram) during sleep. There's a very comprehensive sleep scoring manual which lists all these parameters AASM Manual for the Scoring of Sleep - American Academy of Sleep Medicine (AASM) I've never had a detailed look at that, just read a few papers based on the book. Most of the signals are really tiny and take a lot of filtering to capture and process correctly.
Here's a hypothesis of mine: movement during sleep is a result of mental activity. Try to sit still and notice how some urges and thoughts make you stand up or start doing something. During sleep they might act in a similar way, except that the body is paralyzed and there are no major body movements...
