BrainCap Sizes



International Layout: 10/20 System Electrodes are
distance of 10% or 20% from Cz down to the hat line.

Specialized Equidistant Layout: Electrodes are equidistant to each other via trigonometry calculation.


Cap Cuts:

Both cap types, Subtemporal and SubInion, are available in two cap cuts. One cap cut provides a better fit for more oval/rectangular head shapes and is commonly used worldwide (called “Caucasian cut”).
The other one is cut for rounder head shapes and typically provides a better fit for participants from countries like e.g. Korea, China, Taiwan and Japan (called “Asia Cut”).


Cap Fabrics:

All caps can be made with your choice of two different types of fabric: high-precision fabric and high-comfort fabric.

High-precision fabric is of medium elasticity and has advantages in that it provides a precise reproduction of electrode positions, a longer life span and a quick drying time.

High-comfort fabric is of higher elasticity and works with a variety of head shapes. In the majority of caps, we use the high-precision fabric for adult and juvenile cap sizes and the high-comfort fabric for baby cap sizes.
