DIY Replacement Zeo Sleep Monitor Headband Sensor

Picture of DIY Replacement Zeo Sleep Monitor Headband Sensor
Last year I purchased a Zeo Mobile Sleep Manager. This is a nifty Bluetooth headband that tracks your brainwaves while you sleep and presents it on your smartphone as a graph indicating when you were awake, in light, deep or REM sleep. It's like having your own personal EEG. You can use your Zeo to improve your sleep, test the effectiveness of sleep aids, or to experiment with dream recall or lucid dreaming. As a data junkie, this was something I absolutely had to have!

Unfortunately, the Zeo uses a silver-coated fabric headband sensor that the company says needs to be replaced every few months to ensure optimal performance. These replacement sensor pads are expensive (about $50 for a three pack). Worse, it seems like the company that made the Zeo went out of business last March, so replacement sensor pads are not available at all now!

You can buy a Zeo on eBay, but in order to keep it running indefinitely, you will need to be able to make your own replacement sensor pads. The design of the sensor pad seemed fairly straightforward. After a bit of research and experimentation, I succeeded in making my own replacement headband sensors, and I'll show you how to make DOZENS of replacement sensors pads that will keep your Zeo going strong forever!

DISCLAIMER: Although I have tested these sensors on my own Zeo device, you assume all risks for damage to your Zeo device by making and using these replacement sensors. I am NOT affiliated with Zeo Inc. in any way and did not consult with them in making this sensor.

I make no guarantees about the performance of these handmade sensors vs the Zeo OEM sensors, but until Zeo Inc begins selling them again, I hope this guide will help people who already have a Zeo device and wish to continue using it.

I am desperately in need of a Zeo Replacement Headband. Is anyone making these that would be willing to sell me one/some?

marciot (author) 1 year ago
I wanted to give you guys an update on sensor pads for the Zeo Bedside. I have completed the template for that model and am now in the process of making nine of these for those of you who wanted to buy them from me. I plan to sell them for $15 each, plus shipping. Four of these are already spoken for.

I'll buy, thank you.

If you`re selling the headband for the IOS, I`d be a buyer.

Happy New Year
Any chance you're selling any more of these headbands?

Any chance you could ship them to London?

Thanks,
Mike Cave

Hi everyone, due to possibility of these sensors being protected by patents, and the fact that making these is so time consuming, I will no longer honor new requests for making these for folks. Thank you for your understanding.

I do still have raw materials, so if you wish to have a shot at making one, and do not wish to buy materials in bulk yourself, I might be able to help you that way.

I'll buy some if you are making and selling them. Thank you.

Hi guys,

If there's anyone out there who's got the making of DIY replacement sensors for Zeo down pat, would you mind selling some to me? I'm not good with tools and making stuff and I'm generally too depressed to learn new skills at the moment.

Please contact me at nicety.log@gmail.com if you could help out.

Kind regards,

tolerant

I would like to purchase some replacements as well. I tried other sleep monitors but the headband worked the best for me. What is the best way to buy some replacements.

Many Thanks

I'm not really up to try and make these myself but I'm more than happy to pay. If anyone has working versions for Zeo Mobile I'll be happy to buy them from you for a price comparable to the old retail price. Feel free to contact me onthebrinkbook@gmail.com thanks!

Great instructable! The iron on patches are a great alternative to heat sealing which isn't normally available to a hobbyist. Did you test the resistance of you sensor against the original? I believe Medtex 180 is the same material used in the original zeo headbands but the studs seem to be conductive ABS plastic.

marciot (author)  zeoband5 months ago

The resistance was as good as my old worn out Zeo headband, but I didn't have a new one to compare against. I think it's great that you are trying to manufacture these headbands, but there was another gentleman on here who wanted to do the same and said he was unable to obtain permission to do so from the current IP holder.

marciot (author)  marciot5 months ago

I also personally contacted Ben Rubin, former CTO of Zeo, Inc, and while he was supportive of my work, he confirmed that Zeo and the associated intellectual property rights had been sold to another entity that he was not at liberty to disclose.

So something sneaky is afoot and I'm not sure what it means for Zeo enthusiasts. Maybe a Apple is working on an alarm clock?

Is anybody interested in buying these? I have a small batch being made. If you could email me at zeoheadbands@jrhe.co.uk then I will let you know when they are available.

An alternative is to use ECG electrodes which snap into the sensor. They'll last a few days and you can buy them pretty cheap in packs of 50.

Thanks, Diminished Head! I may give these a try and compare their performance to the fabric sensors :)

BTW, it looks like Zeo Inc also has prototype self-sticking electrodes for sale on Amazon, although they are for the Zeo Bedside (probably because of the snap positions) and the quantity is probably very limited.
Tonight I ran across 2 unused Zeo Headbands and Sensors (packages are opened) if the author or a reader wants to buy. I would sell both for about 80-100 dollars depending if the shipping is too much for me. Considering a guy on ebay wants 700 dollars its a steal.

With the 2 sensors I will give the buyer my high tech advice on a great direction to go with your sleep sensing needs going forward (upon payment only).

I also have an extra bedside mobile unit power and transmitter if anyone is interested in buying that too.

Nice work! Now that the website is no longer available does anyone know of any software that can be used to upload/analyze the data from the SD card?
Thanks soooooo much!

Hi I have been trying to get the double sided foam for the headband in England our DIY and hobby shops don't seem to keep it. Could you tell me how thick it should be or if you know a place I could get it in England.
marciot (author)  Sidx1 year ago
I use 1/16 inch double-sided foam tape, which is fairly typical in the US. The thickness isn't that crucial, but if you can find something slightly thicker, it might be best, as the 1/16th tape is barely thick enough. Have you tried hobby shops, hardware shops, or office supply shops? I am very surprized that this product does not exist on the UK.

You could always order it online internationally:

Good luck!
Sidx marciot1 year ago
Hi Marciot thank you for your help I wasn't sure what thickness to get. I have found ebay to be the best place to get the double sided foam in the end and have bought Black Single Sided Foam Tape 20mm Wide x 6mm Thick. I am not sure yet if this will work I wanted it a little bit thicker as I get marks from the studs over my forehead and have to keep changing the position every night. this is the link: http://www.ebay.co.uk/itm/280762140228?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 My son in law has a laser machine in my garage and has laser'd out the templates for me.
I am hoping to try to put everything together today.
regards,
Sid
marciot (author)  Sidx1 year ago
Hi Sid. Yes, that should work. Double sided foam tape would hold the conductive fabric in place better, especially as you drove in
the studs, but it's probably not a huge deal to make it work with single sided tape. You could use staples around the pads to keep the fabric in place, or maybe tuck the edges of the fabric underneath the sticky side of the tape to secure it. Even if you do none of that, it should all hold together when you iron on the patch. Let us know how it goes, and maybe post pictures of the finished product!

Good that you have a laser cutter, as cutting out the parts is by far the most tedious part of the process.

Does anyone know where to get one of the transmitters? The thing that you snap to the headband? I have one of the bedside Zeos and it isn't receiving signals from the headband any more.
marciot (author)  xinef1 year ago
eBay. Every week a new one comes up. I suggest setting a watch on Zeo.
marciot (author)  marciot1 year ago
Actually "Zeo Sleep" is a better keyword. If you do a completed item search, you'll see that a complete Zeo sells from $50 to $200 each.
xinef marciot1 year ago
Right, so the only solution that you know of is to buy a complete Zeo, no other way to get just the transmitter piece?
marciot (author)  xinef1 year ago
If you watch eBay long enough, you might find someone selling just the transmitter, usually because their base is broken, but that's rare. I think I've only seen it once. Your best bet is to try to get a deal on a complete unit (if it's new and comes with a sealed headband, you could sell that for $75)

An easier solution: buy EKG electrodes (Amazon), a set of EKG leads (Amazon), an elastic headband (hair products and accessories) and Fabric Snaps - Size 16 (Sewing Notions). With the transmitter face down with the three battery recharger laying to the top, this puts the single snap connector on the left, two connectors on the right. Snap EKG electrodes directly onto the left and bottom right female snaps on the transmitter. Take one of the male Fabric Snaps and one EKG lead, shorten the lead and strip the wire about an inch from the cut end of the lead. Wrap the bare wire to the Fabric snap ring and snap this end on to the transmitter in the remaining female snap, cover the bare metal snap with medical tape or HY-tape. Remove the protective paper from the electrodes and place on forehead, cover the transmitter and electrode with the elastic headband and go to bed as normal. I have used this for two weeks and my readings are in line with those done with the "normal" headband.
marciot (author)  gmorgan521 year ago
If you are using EKG electrodes, why not stick them directly to the Zeo, as shown in the picture? I've done this with the AmbuBlu Sensor SP that you can buy online.

The picture comes from the following discussion on the former Zeo forums:

I made my own replacement bands except that I used plastic instead of fabric, the advantages are enormous, instead of sawing you only need instant glue and the plastic retains it's shape and holds the fabric better, plus you can staple it or simply use tape!, in the front part where the forehead would be I used surgical tape which is soft than plastic, I made my first band in 30 mins. which would have taken far longer if used fabric, Check it out!

Yup, there are certainly many ways to skin a cat :) My first prototype was in fact similar to yours, only I used paperboard instead of plastic.
