Overview

The most simple and efficient system for positioning electrodes at designated locations

Developed by Soterix Medical Research, the SNAPstrap™ can be used to position Soterix Medical SNAPpads at designated tDCS/tES locations, maximizing reproducibility and subject comfort. The custom head-gear with fixed electrode sites and built-in cabling makes for a simplistic setup for 1x1 stimulation. Simply open up the pre-saturated SNAPpad™, snap the SNAPpad™ to the cabling at the designated locations on the SNAPstrap™, and load the SNAPstrap™ onto the head. No saturation and carbon rubber electrode setup necessary.

Robust designated position for easy setup
Simplistic self-setup (no medical official needed)
SNAPpad™ access during stimulation, for electrode monitoring and re-wetting during prolonged stimulation
Precise reproduction of electrode positioning for clinical studies

SNAPstraps™ are engineered in three adult sizes (S, M, L) and three pediatric sizes (pS, pM, pL).

What's included

1 SNAPstrap™
