Device "ZMax" with lucid-dreaming functionality
I've seen a lot of devices claiming to be able to detect REM-sleep, and thereby trigger alarms and such to try to induce lucidity. Some of these seem promising to me (including a custom approach I'm currently building with the Muse S), but I recently came across one that takes the cake in terms of the amount and detail of data it captures.
It's called the "ZMax" sleep-research device. You can search "zmax lucid dreaming" for its application to lucid dreaming specifically. (not linked directly due to possible issue with forum rules)
Anyway, one thing I should be able to link is to this Youtube video, which shows rem-periods in the captured data: https://youtu.be/w7qJovmL7u8?t=900
As far as I know, the fidelity of the data that makes the rem-detection shown there possible is the best available on the market currently.
However, there are two big negatives of it:
1) It uses "non-dry" electrodes, meaning you have to use gel to place the eeg sensors on your head each night. This is more of a hassle, and also means some amount of maintenance cost.
2) It's really expensive! According to this paper (https://www.researchgate.net/publica..._They_Reliable), it costs around $900 -- which is way too much for most people.
So, unfortunately I won't be trying it myself either -- both because that's expensive for me personally, and because, even if a reliable induction procedure were developed based on it (enough to be worth it for me), it still wouldn't be a solution that could be "used by the masses", which is what I (and many others) ultimately aim for.
Thus, I'll be continuing to work on procedures using cheaper devices (like the Muse S, at ~$300). But I figured it was worth making a post about the ZMax as well -- as a standard to which other devices can be compared, and for the rare enthusiast who has a spare thousand dollars lying around. ^_^
