1×1 tDCS Device
Transcranial Direct Current Stimulation featuring one anode and one cathode
Soterix 1×1 tDCS Device
Precision transcranial Direct Current Stimulation device for conventional tDCS.
The Soterix 1×1 (one anode and one cathode) tDCS stimulators are very simple to use, precise, reliable, and economical. Soterix 1×1 stimulators are designed especially for tDCS, based on extensive feedback from leading clinical centers.
The Soterix 1×1 tDCS stimulators allow simple selection of:
- 4 current settings (up to 2 mA)
- 4 duration settings (up to 40 minutes)
with count-down clock display - Sham feature

1×1 Limited Total Energy (LTE) tDCS Device
Designed for stimulation of susceptible subjects
Soterix 1×1 LTE Device
Innovative adaptive ramp-up stimulation technology for susceptible populations.
Limited Total Energy Transcranial Direct Current Stimulator (LTE-tDCS) was developed exclusively by Soterix engineers. LTE limits the voltage required for tDCS through the use of adaptive ramp-up stimulation. Should resistance increase to atypical levels, LTE-tDCS will automatically reduce the applied current so as to maintain a low voltage.

Soterix EASYpads™ available in three standard sizes (5x7, 5x10, 10x10 cm) or custom sizes to order. Disposable EASYpads™ replacements can be purchased in economical packages of 100.
Elastic fastener with plastic joints for simple positioning of electrodes on the head
Soterix elastic fastener can be used to position Soterix EASYpads™ comfortably and simply on the head. All head sizes and most standard electrode positions can be accommodated with a single re-usable fastener kit.
Soterix EASYstrap™ - The most accurate and fast system for positioning electrodes at standard locations
Developed by Soterix Medical Research, the EASYstrap™ can be used to position Soterix EASYpads™ at standard tDCS locations, maximizing reproducibility and subject comfort. The custom head-gear with engraved land-mark finder and ruler makes the EASYstrap™ the simplest system to use for tDCS. Simply identify the standard tDCS electrode locations, snap in the EASYpads™, and secure the EASYstrap™ to the subjects head with a single safety buckle click. Additional EASYstrap™ benefits include:
- Robust fixed position, even under moderate subject motion
- EASYpad™ access during stimulation, for electrode monitoring and re-wetting during prolonged application
- Precise reproduction of electrode positioning for clinical studies
The EASYstrap™ is engineered in three sizes (specific S1, M1, L2) and buckle types (specify Snap, Safety Buckle, Velcro).
