This revolutionary dry EEG acquisition system requires no gel, no paste and no wires. Freedom is here!

The Freedom 24D is a research grade wireless EEG headset designed for rapid application of 21 sensors at locations corresponding to the 10-20 International System.

  • Dry Sensors: High quality through hair EEG without skin abrasion or gels
  • High Fidelity EEG signal: Comparable to that obtained with wet electrodes
  • Low Noise: Patented circuit design reduces environmental noise
  • Practical Headsets: Self-donned in less than 5 minutes and comfortable for hours
  • Wireless: Integrated amplifiers, digitizers, and Bluetooth transmitters
  • Motion Artifact Resistant: Mechanical isolation enables ambulatory use

Applications

The Freedom 24D's practicality, portability, and high signal quality opens the door to taking numerous applications that were previously limited to lab environments to more naturalistic settings. Such applications include:

  • Neurofeedback
