1×1 tDCS Device

Industry Standard transcranial Direct Current Stimulation

The Soterix Medical 1×1 is the clinical standard device when precision and safety cannot be compromised. The Open-Panel™ control panel allows simple set-up and monitoring. Exclusive features including SmartScan™, Relax™, and TrueCurrent™ ensure every run is successful.

Industry Standard For Clinical Trials

The Soterix Medical 1×1 was developed by clinical researchers, scientists, and biomedical engineers to provide all clinical standard tDCS protocols. Current intensity from 0.5 to 2 mA, and current duration from 5 to 40 minutes. Stimulation set-up is straight-forward with the simple to set-up Open-Panel™ controls, 1×1 electrode accessories, and SmartScan™ indicator. The tDCS 1×1 features allow you to focus on the subject and experiment, not the device.

Our scientific team is ready to work with you to determine optimal dose parameters and accessories.

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.*

*Due to ongoing dose and surge concerns about unverified “tDCS” devices and off-label DC sources (such as iontophoresis units counter-indicated per FDA guidelines for use on the head), Soterix Medical Inc. can no longer provide tDCS accessories, HD-adaptors, neurotargeting software, or Solution Support for unverified devices by other manufacturers.

Advanced real-time control and optimization

Simple to use

Open-Panel™

In developing the 1×1, feed-back from leading clinical centers was clear: tDCS must be simple to program and stimulation status must always be apparent to the investigator. With easy-click control knobs 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 guess work out of tDCS.

No drop-down menus. No hidden settings. No external computer.

Device Features

Each Soterix Medical 1×1 feature was developed by our team of biomedical engineers consulting closely with leading clinical centers. Designed to simply set-up, provide intelligent warning of a fault condition, and allow for adjusting 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 1×1 tDCS.

Provides a continuous visual indication of electrode quality before and during stimulation.

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.

Clearly indicates the actual current supplied at the moment.

What other devices promise, the 1×1 tDCS delivers. The back-lit display can be monitored during stimulation ramp up and to confirm target current intensity is achieved.

May be used to supply a very weak current prior to tDCS to help condition the skin.

Tickle™ may be used to both condition skin prior to tDCS and for naïve subject anxious about stimulation. A custom on-off waveform pattern generates mild and brief sensation under electrodes.

Allows the clinician to use a simple sliding bar to transiently decrease the current from the pre-set value, for example based on subject feedback.

Based on feed-back 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™ slider may be adjusted from full to reduced intensity based on subject perception without interrupting or aborting stimulation.

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 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 of stimulation, and again after 10 minutes, with the timer automatically adjusted such that the total run time us exactly matched to the real case. Based on the Soterix Medical OpenPanelTM design principle: with no complicated programming or hidden drop-down menus required.

Limited Total Energy for Clinical Trials.

The same advanced power-managment system using 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 tDCS model.

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 if required from the simulator for theoretically maximized EEG S/N.

Compatibility with monitoring technology

With increased interest in the use of monitoring, such as EEG, PET, MEG, Eye-tracking, NIR and fMRI in conjunction with tDCS, Soterix Medical remains the only company with the technology and expertise to ensure successful integration. Stimulation generates artifacts in all monitoring modalities including fMRI (Antal A et. al 2012), such that use of technically compatible devices without also integrating rational trial design, can lead to errant findings.

Soterix Medical biomedical engineers are available to discuss the combination of rational measurement with our industry standard 1x1 platform. And only Soterix Neurotargeting allows co-registration of current flow and measured responses
