Description

The DSI-7 by Wearable Sensing is a research-grade wireless dry electrode EEG headset designed for ultra-rapid application of 7 individually placed sensors at the F3, F4, C3, C4, Pz, P3, P4 locations of the corresponding 10-20 International System. It is self-donned and fully setup, ready to record EEG in under 1 minute. Designed for great comfort it can be worn continuously for over 8 hours. It's portable design is suitable for any light ambulation in office or lab environments. The system has active sensors in form of linked-ears earclips. The DSI-7’s practicality, portability, and high signal quality opens the door to taking numerous applications that require rapid and non-intrusive EEG recording. Such applications include:

  • Neurofeedback
  • Neuroergonomics
  • Neuroeconomics / Neuromarketing
  • Augmented cognition
  • Brain-computer interfaces
  • Biometrics
  • Cognitive stress or workload monitoring
  • Psychological Research
  • Sports Peak-Performance training
