  • The Ultracortex “Mark IV” EEG Headset starts from 400 USD in the www.OpenBCI.com shop and has a proof of function which is shown on the YouTube demo series from Sendex (3 parts).
  • The Ultracortex “Mark IV” alternatives sold on Aliexpress and eBay which is more affordable the Ultracortex.
  • OpenBCI Galea mentions in the description that the device uses the most comfortable dry electrodes which are available.
  • g.tec medical uses semi dry electrodes.

We studied this previously and have published it in our journal. We think it is worth to do more research about this topic.
