The Free-Cap is our newest type of EEG-Cap, which uses water (saline) as conductive. The electrodes are mounted into a holder together with a special sponge-like material, which slowly releases water to the scalp. This leads to excellent impedances in a short time without much scratching and painful procedures. The use of this EEG-Cap is primarily provided in the area of neurofeedback. However, the clinical EEG can also be recorded with Free-Cap. It allows to work with 1 - 19 electrodes and ear clips or mastoid electrodes. It works with DIN-Plugs, so it is compatible with most of the EEG-Devices that are avalable on the market.
In the Free-Cap User Group on Facebook you can share your experience with Thomas Feiner´s invention the Free-Cap, the alternative that really works without paste and gel. There is no cleaning of the paste, no paste on your finger on your client or on your precious instruments. The Free-Cap is what you have been looking for a long time. It´s affordabable, durable and easy to use. And you save money from not paying for gel and paste.
This Cap is a new product for everyone who is doing Neurofeedback professionally.
EEG-Training and Assessment without Gel and Paste? Here is your alternative with using only water and tiny amount of salt (table salt is sufficient!)
We recommend to use only a tiny amount of abrasive if the skin and hair is very oily. But only a very few applied with a cotton bud and you get great EEG readings!

FAQs
Q: what must I do to get good impedances?
A: if you buy a set you get the sponges already mounted into their holder with the electrode. Just fill a glass with saltwater and soak the electrodes with together with holder and sponge into the saltwater for about 10 seconds. Then mount the holder to the desired places on the Free-Cap.
Q: can I use other sponges than you offer on the website?
A: no these are special sponges you cannot buy them in regular shops or supermarkets
Q: how long to the sponges last?
A: about 3- 4 month
Q: how can I clean the sponges
A: it is recommended to use 70% alcohol
Q: when do I need to replace sponges?
A: when you do not get good impedances anymore it is possible that the sponge needs to be replaced by a new one. You get always the best readings with newer material. We recommend you purchase a pack of spare sponges.
Q: how should I assemble the sponge into the holder?
A: put the electrode into the holder, make sure the electrode shows it´s "face" up. Take a DRY sponge pad and press it gently into the holder so that it is well covered by the edges of the holder. Make sure the sponge is below the edges, you may need your finger nail to press the sponge into it´s housing.
When you want to replace a sponge it´s better to do this with a wet sponge.

This leads to excellent impedances in a short time without much scratching and painful procedure. The use of this EEG-Cap is primarily provided in the area of neurofeedback. However, the clinical EEG can be deduced in the same way. It allows to work with 1 - 19 electrodes and ear clips or mastoid electrodes
Positioning the electrodes
We found out that especially beginners love to use our Free-Cap. No you can find those positions like P3 and P4 or F3 and F4 very quickly.
The Free-Cap rubber foam net fits to many different head shapes and sizes.
Ear clips or Mastoid placement?
The Free-Cap per default comes with electrode holders on the mastoid position. But you can of course use our new ear clips which work with the same electrodes. Also, we redesigned our ear clips so that the pressure can be adjusted. They are extremely light weighted and you hardly can perceive them on the earlobes.
Ear clips are recommended when you see a lot of ECG in the EEG.
Chin straps or chest belt?
Our chin straps are usually very comfortable, but sometimes a chest belt is better. Our universal chest belt just uses Velcro band, is very flexible and makes wearing of the cap very comfortable too. People with a very sensitive neck or skin prefer the chest belt.
FAQ:
“Do you need to add saline to the sensor sponge after you have soaked the entire cap in saline? Do you also need to prep the scalp under each sensor or is the saline enough? Also how much water should be added to one salt tablet?”
-You do not need to do this with all electrodes. There are sometimes positions where the skin really needs some preparation as saline cannot go through oil on the skin. Only very little abrasive on the tip of a wooden cotton stick is usually enough. Also, sometimes your sponge may have not have been wet enough. Just spray some water onto the sponge or use a syringe with a blunt needle and inject some salt water you can also do this from above by injecting water beneath the rubber string. But a water spray works very well to provide you with good signal quality.
Please take about 5-8 pills from the salt tablets and solve them in water. After they solved in the water (quarter of a liter or a half liter, depending on what you use to put the Free-Cap in.

Feedback of some of our users:
"A great invention...I have the highest praise for the Free-Cap. Once you use it, I can't imagine that you would ever want to go back to the paste method. In my experience, connectivity is superior, even with ISF. I have found it to be successful with all types of hair. Both clients and technicians are thrilled to have neurofeedback without the mess."
Amy Warren
"Die Free-Cap ist in jeder verfügbaren Variante absolut empfehlenswert. Ob 2-, 4- oder 19-Kanal, die Kappe ist leicht zu handhaben und wird von den Patienten als sehr angenehm empfunden. Auf technischer Seite stellt sie auch einen deutlichen Fortschritt dar: Impedanzen unter 5 kOhm sind mit etwas NuPrep oder OneStep recht leicht zu erreichen, das EEG Signal ist schön klar. 2 angenehme Zusatz-Effekte: Die Haare sind nach dem Training nicht voller Kleber (gerade bei weiblichen Patienten positiv wahrgenommen) und wenn ein Kind nach der Verkabelung dann doch noch entscheidet, dass die Schuhe ausgezogen werden müssen und sich nach vorne beugt, bleiben mit der Kappe alle Elektroden an Ort und Stelle."
Philipp Heiler, Arzt und Neurofeedback-Therapeut
“Thomas Feiner's EEG caps are a new, excellent and needed innovation. The cap is easy to apply and comfortable. It is also unique in that one can simultaneously record EEG while presenting stimuli and other treatment modalities."

"I hope you had a booth at ISNR---neurofeedback practitioners need to know about this cap, esp those doing whole head assessments and 19 chan surface and Loreta.
So much quicker to use, easy to get good low impedances, much more comfortable for the patient.
Also, I've a few women patients who only come at the end of the day, because my regular cap messes up their hair. Yours--negligible inconvenience.. Not a lot of folks to give me feedback yet, but I can see the cap is more comfortable to wear as well.
Also an advantage with 4 channels or less. I've a DBA so I can use your full cap version with my Atlantis. Though I might like to purchase the net and several individual electrodes. I'll keep you posted as more people try it. I especially like being able to lift up the electrode, touch w NuPrep on the scalp, put the electrode back, and impedance is down--with no discomfort to the patient.
I've one patient who is the most difficult patient in 36 years to hook up. I'm looking forward to her coming in.
Hope your cap is success. You deserve to make lots of money on this one. a great contribution."
Dr. Dick Genardi, Ohio
"I'm really enjoying the cap and you can get great signal in no time !"
Dr. Doron Todder
"I bought a 4-channel FreeCap from Thomas Feiner at ISNR, and tried it out on myself today. To tell the truth I was a bit skeptical when I bought it but "banked" on Thomas' reputation. The cap produced beautifully clean EEG that you could tell came from low impedance (5-8 Kohms) and DC around 1 to 3. I was using the Discovery amp but will now also buy an adapter so I can use it with the Atlantis amp."
Dr. John M. Griffin
From the Facebook Free-Cap-User-Group
Thanks for adding me to this group. Like all things that combine simplicity of concept with with a touch of genius this is a breakthrough that will enhance the use of EEG especially in psychiatry where messing up the hair is often met with negative patient related attitude and hence unwillingness for follow up EEG's. I admire your inventiveness and creativity. This is a hit that I will not fail to promote.
Dr. Georges Otte
