Thread: REM Detectors (again)

Hello every body,

I am new comer in this forum (and in lucid dream resarch), and i would like to know if it is the right place for debates about piezo sensors for eye movement detection. The start of the thread was a little general but it seems that you ve been focusing on GSR since a while, so if you want me to deplace my response, just tell me.

I ve been actually awared by a specialist that IR could actually warm the liquid contained inside the eye ball without any alarm from our senses because illumination occurs behind the "right place" (i don't know the english word for it"). Then, for a home made device, i think this technologie is a little bit unsafe.
So, i 've been looking for another way, and i found out that the NASA, has actually used piezo sensors, for eye movement detection, monitoring that way paradoxal sleep.
Here is the kind of sensor i am talking about:

What do you think of it? any specialist around for a new dream mask generation (USB 2.0 required)
