Product DSI-24


The DSI-24 is a research-grade wireless dry electrode EEG headset designed for rapid application of 21 sensors at locations corresponding to the 10-20 International System. Its main features include

  • Self-donned and ready to record EEG in under 5 minutes
  • Comfortable for wearing continuously over 8 hours
  • Portable design suitable for light ambulation in office or lab environment
  • 21 sensors positioned according to the 10-20 International System
  • Continuous impedance monitoring
  • Bluetooth wireless transmission with sampling at 300 Hz
  • Hot-swappable Li-ion batteries allow continuous operation
  • 8-bit digital trigger input
  • Adjustable to fit a wide range of head sizes (54-62 cm in circumference)
  • D-Lab Pic


    The DSI-24'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
  • Neuroergonomics
  • Neuroeconomics / Neuromarketing
  • Augmented Cognition
  • Brain-Computer Interfaces
  • Biometrics
  • Cognitive Stress or Workload Monitoring
  • Psychological Research
  • Sports Peak Performance Training

    Child-Sized Version: DSI-24-C

    The DSI-24's practicality, robustness to motion artifacts, high signal quality, and unsurpassed comfort beckoned for a version suitable for children.

    And, thus, by popular demand, we have developed a smaller version of our DSI-24: The DSI-24-C, which is designed to comfortably and accurately position the dry sensors on heads 48-54 cms in circumference, thus fitting >90% of male children 3-7 years of age, and >90% of females 4-9 years old. (The DSI-24 optimally fits 54-62 cm) This unit is thus an excellent complement to a DSI-24, or can be purchased separately, as the child-sized version is a stand-alone unit, and includes its own integrated amplifiers, digitizers, and 19 sensors on the head at the International 10/20 System locations, as well as 2 removable earclips and 1 auxiliary input for ECG/EMG/EOG.
