I B V A : Interactive Brainwave Visual Analyser
The IBVA / Brain Duino / Brainmachines are all super highly sensitive EEG monitors communicating via  bluetooth. The original model was designed over 30 years ago in Japan, the same team still develop the software and the hardware, made in small quantities in the USA and Europe. They ship in a protective aluminium carry case with a choice of  2 or 4 channels and either the 3 electrode sensor or the 5 electrode version.

All BrainMachines use sensors that can connect to different electrodes, capable of measurement through hair (with the addition of TENS gel & adhesive electrodes). Begin with Pre-frontal monitoring , or  adhere the other electrodes anywhere on the regions of 10:20 EEG monitoring.

Detailed hardware specifications

• bluetooth EEG interface: 2m – 20m transmission range
• high quality state of the art amplifier board
• dynamic electrical range  : 0.2 mV to 200 mV
• programmable sampling rate: 120 Hz to 1920 Hz
• programmable high cut filter 12 Hz to 900 Hz

 

 

 

 

 

Both 2 channel and 4 channel IBVA Brainmachines, fit inside once case – weight 1.2Kgs per system


 

 

 

 

 

 

 

 

 

The EEG sensor commonly used is the 3 electrode grey/blue strip, easy to apply in one piece across the forehead with a small earclip for reference. For an additional £65 the 5 electrode cable can be ordered to allow 2 channels not so close together to be monitored with the mastoid used as reference with an electrode placed there.

New design sensor cable allows ‘free placement’ of the electrodes, commonly we monitor the Frontals (above each eye) for decision making or the Occipitals above the  brainstem on the back of the neck for the visual processing region of the brain. Pre-gelled electrodes are best for bare skin on the forehead, and the washable electrode discs with  TENS gel and a medical skin preparation cream are needed for sites where hair is present to adhere and get a good signal, these are supplied in a kit for an additional £50.

The whole kit fits inside a 22cm x 17cm case, so its incredibly portable and easy to take on adventures. The main ‘BlackBox’ is the brain machine, this hardware component is the digital sampling unit and amplifier, a two or four channel device powered by internal battery. This can be worn in a holder like a camera pouch or tucked in a shirt pocket when moving around, as the neuro-data is sent wirelessly to the host computer for analysis. The  pre-gelled medical electrodes are attached to the forehead , detecting brainwaves and their signals sent into the brainmachine via a small cable. Three electrodes per session or per person are required to ensure good conductivity and swabs of alcohol cleanse are wiped over the skin first to prepare it, de-grease and improve recording quality.


Every  system contains :

•Full IBVA5 software dvd (updates online)
•bluetooth brainwave amplifier (main unit) - (optional distance achieved with bluetooth dongle amplification)
•sensors cables for 2 or 4 channels, a ‘snap-on’ electrode terminates each one
•soft headband to hold electrodes firmly to the head
•medical disposable electrodes x 50
•internal charging battery
