Mobile-72 Wireless EEG System

Have you every wondered what was inside your EEG system that made it so large? In developing our wireless EEG products, we realized that a new generation of miniature, low-noise data acquisition systems that are small enough to be wearable was needed. 

The Mobile-72 is an ultra-portable high-density EEG system. The entire system fits on a cap and weighs only 250 grams providing the ultimate level of subject freedom. The cap uses standard Ag/AgCl electrodes for high-quality EEG measurements.

 

Ultra-portable

With the Mobile-72, hardware size and weight are no longer limitations to conducting EEG research. The wearable system is suitable for studies involving unconstrained, full body movement or outside the laboratory in real-world settings.

  • Virtually no restrictions or limitations on subject's freedom to move
  • Portable EEG amplifier streams data and time markers wirelessly
  • Record to an onboard microSD card for long-term studies
  • Entire system fits on cap and weighs only 250 grams; no cords, loose wires or backpacks

Research-grade Signal Quality

The Mobile-72 is based around the same advanced electronics as our dry EEG headsets, including identical amplification and shielding technology. This offers an unparalleled level of signal quality in all environments and even under ambulatory conditions.

  • Active shielded Ag/AgCl electrodes secured in cap, ensures highest signal quality even under subject motion
  • Immune to most electrical and mechanical artifacts
  • Up to 64 channels of EEG, 8-channels of auxiliary inputs for true high-density EEG
  • Real-time impedance check to guarantee adequate sensor contact and assist with rapid setup
  • 24-bit ADC, high-dynamic range inputs with flexible configuration of sample rates, bandwidth and channels

Versatile

Like all Cognionics products, the Mobile-72 is designed to interface with all of the hardware and software tools necessary for advanced neuroscience research.
