Soterix 1x1 tDCS Device - Industry Standard For Clinical Trials
The Soterix Medical 1x1 was developed by clinical researchers, scientists, and biomedical engineers to provide all
clinical standard tDCS protocols. Current intensity from 0.1 to 5 mA, and current duration from 5 to 40 minutes.
Stimulation set-up is straight-forward with the simple set-up Open-Panel controls, 1x1 electrode accessories, and
SmartScan indicator. The Soterix 1x1 features allow you to focus on the subject and experiment, not the device.
Stimulation Precision and Control
The Soterix Medical 1x1 platform is the most accurate tDCS technology available. Built into every 1x1 device are the
most advanced monitoring and control systems updating performance and feedback over 1000 times per second.
Stimulation output fidelity (signal-to-noise) is maintained during the entire stimulation session even if electrode
conditions change. Precise control of output waveform is essential for stimulation efficacy and safety.
Clinical trials with Soterix Medical 1x1 tDCS remove uncertainty about device output and ensure results are
meaningful and reproducible.
Simple to use Open-Panel
In developing the 1x1, feed-back from leading clinical centers was clear: stimulation must be simple to program and
its status must always be apparent to the investigator. With a simple press of a button to set stimulation duration
and intensity, and back-lit status displays visible in dim or bright room light, the Soterix Medical Open-Panel
design takes the guesswork out of the stimulation.
No drop-down menus. No hidden settings. No external computer. Designed for simple and
clear clinical trials with Soterix Medical Open-Panel.
Each Soterix Medical 1x1 feature was developed by closely consulting with leading clinical centers. Designed to
simply set-up, provide intelligent warning of a fault condition, and allow for adjustments for patient comfort,
these features facilitate reliable and tolerated tDCS. The Soterix Medical SmartScan feature is central in all tDCS
devices to allow reliable set-up and monitoring. The RELAX, Tickle, and TrueCurrent innovations were developed for
the 1x1 tDCS.
Smartscan: Provides a continuous visual indication of electrode quality before and during
From pre-stimulation set-up, to during stimulation monitoring, to post-stimulation
confirmation, the Soterix Medical SmartScan feature provides an intuitive and clear indication of electrode
contact quality. Use the SmartScan™ during set-up to adjust electrodes and head-gear for optimal fit. During
stimulation, SmartScan provides a constant indication of electrode quality and can be monitored during
adjustments (e.g. addition of saline to drying electrodes). After stimulation, SmartScan confirms a successful
trial. Because “resistance” is not meaningful for tDCS, SmartScan was developed by Soterix Medical engineers to
provide clinical investigators with a simple to read indication of contact quality.
Relax: Allows the clinician to use slider buttons to transiently decrease or increase the current from the
pre-set value, for example, based on subject feedback.
Based on feedback from leading clinical
centers, Soterix Medical exclusive feature, RELAX, accommodates subjects who may be anxious when stimulation is
initiated or during the course of stimulation. The RELAX level may be adjusted from full to reduced intensity
based on subject perception without interrupting or aborting stimulation.
Auto Sham: Simple and intelligent sham waveforms.
An automatic stimulation sham feature that is engaged
with a simple switch. Auto-sham automatically calculated and produces a sham waveform based on the indicated
“real” waveform. For example, for a corresponding real waveform of 1.5 mA and 10 minutes. auto-sham will provide
a ramp up/down to 1.5 mA at the start of stimulation, and again after 10 minutes, with the timer automatically
adjusted such that the total run time is exactly matched to the real case. Based on the Soterix Medical
Open-Panel design principle: with no complicated programming or hidden drop-down menus required.
True Current: Clearly indicates the actual current supplied at the moment.
What other devices promise,
the 1x1 tDCS delivers. The back-lit display can be monitored during stimulation ramp up to confirm that the
targeted current intensity is achieved.
Tickle: May be used to supply a very weak current prior to tDCS to help condition the skin.
be used to both condition skin prior to tDCS and for naive subjects who are anxious about stimulation. A custom
on-off waveform pattern generates mild and brief sensation under electrodes.
toDCS: transcranial oscillating Direct Current Stimulation.
Request this special mode for the only devices
designed for precise modulated direct current stimulation. toDCS includes all the features of standard 1x1 tDCS but
provide only oscillating direct current waveforms.
LTE-CT: Limited Total Energy for Clinical Trials.
The same advanced power managment system used in the
1x1-Clinical Trial devices available only by special request on the 1x1-tDCS. CT-LTE provides a unique power and
voltage limited technology, exclusive to Soterix Medical. For conventional LTE, limited to 1.5 mA, use the 1x1-LTE
⁺EEG: The lowest noise tDCS device ever, for combination with EEG recording.
Available only by special
request, the +EEG mode on the 1x1-tDCS is a unique device especially designed for combination with EEG recording.
All standard 1x1-tDCS devices already provide industry standard precision and low-noise output control. The +EEG
mode of the 1x1-tDCS is a unique product only for EEG application where “floor level” noise is required from the
simulator for theoretically maximized EEG S/N. Contact Soterix Medical professional support for guidance.
