Mind-Fi

Applications < Event-related potentials <

The closest thing to mental telepathy you’ve ever seen!

Mind-Fi is a wireless 63 channel active EEG head-cap that enables participants to project their thoughts in real-time anywhere in a coverage area of 20x20 feet (6x6 meters). Active electronics on the cap eliminate the need for scalp abrasion resulting in cap setup time of only 5-10 minutes. The cap weighs only a few ounces, so it’s comfortable to wear and it will stay put as subjects move through the environment. To wash, just remove the tiny transmitter and place it on the charger.

There’s also a small wireless receiver to instantly receive the projected thoughts, flexible data acquisition hardware and powerful, easy-to-install data acquisition software for any Windows platform. Mind-Fi is suited to EEG, ERP and even BCI studies.

Features and Benefits:

Quick setup and unexpected signal quality: Active head-stage on the cap, battery power and electrical isolation
Compact: 63 channels on the cap and receiver
Easy to install on any computer: USB 2.0 interface with Windows,MAC and Linux drivers
Wide range of applications: 0.8 to 2 kHz frequency response
No need for shielding, so you can use it almost anywhere: inherently isolated, high input impedance and high CMRR for superior noise rejection
Inexpensive, state of the art DAQ options: 16-bit burst-mode sampling or one 24-bit A/D per channel, simultaneously sampled
Any electrode layout is possible: A wide range of standard and customizable head caps
Software choices: Simple, full-featured turnkey software or MATLAB API
You own your data: Uses standard EDF data file format, which is supported by almost all available EEG analysis software tools
