A lot of products use accellerometers as a proxy for sleep it’s cheap and can provide good data. For me though, I wanted to monitor my brain and the Zeo sleep tracker is basically the only one of its kind.
The Zeo is a headband with three pads on it. These pads are woven with metal, which makes good electrical contact with the skin without being as annoying to place as the electrodes during my sleep study. The Zeo is not a medical device and won’t give as accurate results as a clinical sleep study, but it is very good for what it does.
The Zeo divides sleep into a number of types: awake, REM, light and deep sleep. The headband uploads its data over Bluetooth to my mobile and from the mobile up to the Zeo website.
It’s pretty easy to set up and use, but I’ve had great difficulty using it during Brisbane summers on those hot sultry nights every extraneous bit of clothing just increases the discomfort.
The Zeo website makes it trivial to download all of the data in a simple, detailed format, which is perfect for my use.
