Neuromodulation techniques like tDCS are only as good as the head-gear you use.The Caputron Universal Strap was developed by Caputron engineers to address a broad need for simple tDCS head-gear capable of reliably positioning sponge electrodes on the head with the same accuracy as the headstraps used in clinical trials. The Caputron Universal tDCS Strap allows for simple and reliable positioning of any combination of sponge electrodes, like those used for tDCS, in any position on the head. In contrast to a cap, the Universal Strap allows you to see where the electrodes are positioned and to fix saline levels without needing to remove the pads or the strap. Our headstrap is easy to set up and provides excellent electrode contact quality. For best results use the Caputron Universal Strap, your one stop solution for all tDCS montages!

How to Use

The Caputron Universal Strap is extremely simple to use and adjustable in size.

1. Push or pull the rivets to loosen or tighten the straps respectively.

2. Place the long strap against your forehead and secure the strap on your head by attaching the velcro strap either under your chin or along the back side of your head.

3. Move the short strap and place it along the top of your head.

4. Strap size may be adjusted by first removing the strap from the rivets. This is done by streching the material over the rivet. Next place the rivet through the desired hole that best fits to your head.

Electrode Placement System Explained

The Caputron Universal Strap is used to easily reproduce some of the most common tDCS montages. Using the Caputron Universal Strap in combination with the 10-20 EEG system, users are able to match the precision and reproducibility in electrode placement achieved by researchers and clinicians.

The 10-20 EEG system is an internationally recognized method of sectionalizing the scalp. This method is done by assigning a lobe letter, F (Frontal), P (Parietal), T (Temporal), C (Central), or O (Occipital) in combination with a hemisphere number, even for right hemisphere and odd for left hemishphere. For example, F7 stand for Frontal 7 located in the left hemisphere. This system provides a standardized method of comparing electrode positioning between subjects.

    To measure your EEG markers for tDCS electrode placement - Follow these steps
  1. Measure the distance from the nasion, the depressed area located just above the bridge of the nose, to the inion, identified by the noticable buldge on the back of the skull.
  2. Mark the halfway point between these points.
  3. Measure the distance from the tragus to the tragus.
  4. The interesction of these points is the vertex of your skull, known as Cz.
  5. Use these mearuements map electrode placement in respect to the standardized EEG mapping.

It works

Very nifty and adjustable. I have only tried it a couple of times, still wondering what it will do that the regular elastic strap doesn’t. I probably need some written explanation to make best use of the strap.

It's nice.

Very easy to use.


I can even use it for neurofeedback.
