The 1x1 platform stimulators are the most precise stimulators ever made for non-invasive electrical stimulation, including unique control features not available on any other products.
Better technology means better outcomes. Soterix Medical believes that in advanced neuromodulation one size does not fit all, the 1x1 platform includes three stimulator devices, upgradable adaptors, and state-of-the-art accessories customizable to your needs.
In advanced neuromodulation “one size does not fit all”. A single design that tries to achieve everything, compromises everything leaving subjects at risk. Soterix Medical devices and accessories allow simple configuration and customization.
Soterix Medical is the trusted leader in tDCS and related technologies because we provide clinicians and investigators with the only accessories designed for tDCS/tPCS/tACS/tRNS.
Conventional tDCS uses one anode and one cathode (1x1) with tremendous possibilities for customization and optimization. The Soterix Medical 1x1 line of stimulators provides clinicians with the right solution. The selection of the right stimulator for your objectives is central for rational tDCS/tES.
To understand the Soterix Medical's Open-Panel interface, one needs to consider how tES and tDCS are applied in the best clinical and academic centers. The risk of relying on a wireless connection with a computer to control and monitor the device is not acceptable. Similarly, complex and hidden drop-down menus create inherent risk in programming mistakes. A single mistake can compromise subject safety and the integrity of an entire clinical trial. For medical grade equipment, device status and subject monitors should be clearly visible on the device display. Soterix Medical devices, including features such as Open-Panel, are chosen when patient tolerability and trial integrity cannot be compromised.
Avoid confusion and mistakes. Save time. 1x1 devices can be programmed in seconds with simple switches and controls.
With stand-alone 1x1 stimulators, there is never a need to use a personal computer for interface. This reduces your cost, complexity and potential errors.
Easy to read displays, even at a distance and even in reduced light conditions, means you always can monitor stimulation status.
In advanced neuromodulation, one size does not fit all. Display and control items are minimized to what you need. Clarity and simplicity without compromise.
A single programming error undermines reproducibility and safety of an entire trial. Open-Panel reduces errors even under multiple-user or high-throughout conditions.
No risk of computer or connection failure leading to loss of device control. Risks associated with computer failure (e.g. during a software update) are avoided.
Device settings and current state are always visible to their operator. Intelligent SmartScan testing provides early warning of poor contact conditions.
Devices prevent current transients even under unexpected conditions such as sudden re/dis-connection. Soterix Medical is the trusted leader in tES by designing safety factors for the unexpected.
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 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 the stimulation.
Each Soterix Medical 1x1 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.
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
May be used to supply a very weak current prior to tDCS to help condition the skin.
Tickle™ may be used to condition skin prior to tDCS and for naïve subjects who are 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.
For susceptible subjects, Limited Total Energy minimize power and energy delivery
Limited Total Energy for tDCS (LTE-tDCS) was developed exclusively by Soterix engineers. LTE limits the voltage and power required for tDCS through the use of adaptive ramp-up stimulation and intelligent energy management.
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 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 Open-Panel™ design principle: with no complicated programming or hidden drop-down menus required.
Full integrated clinical trial support with subject codes and customized sham protocols
Developed to support multi-center clinical trials in tDCS. Double Blind from Soterix optimize well beyond traditional ramp up/down shams. For true operator blinding, device operation must balance providing a continuous indication of stimulation and electrode quality status for safety, without betraying whether the stimulation session is real or sham. Since “one size does not fit all,” Soterix Medical scientists work with you to customize Double Blind to your active protocol and electrode montage.
A simple feature that minimizes dropout in double-blind clinical trials
Sometimes trivial issues require stimulation interruption or adjustment. Rather than abort a session which can result in subject exclusion or data confounds, the PAUSE feature was developed in collaboration with clinical trial experts running higher-volume or longer duration trials. For both automatic (under SMARTScan) and user initiated PAUSE, this exclusive feature intelligently avoids breaking sham even in double-blind trials.

Soterix medical offers unique, custom solutions to easily integrate 1x1 Platforms with fNIRS, EEG, fMRI, and other monitoring modalities for a streamlined research experience.
Increased subject comfort with an extended adaptive ramp.
In order to improve stimulation comfort and tolerability, 1x1 platform devices allow up to 60 seconds ramp for stimulation at intensities higher than 2 mA.
Every 1x1 accessory is optimized for simple and consistent set-up, robust and safe performance, and ease of use. Since "one size does not fit all" in tES, the 1x1 accessory set provides the flexibility to optimize performance. From EASYpads™ to EASYstraps™ Soterix Medical 1x1 accessories are designed and validated specifically for the 1x1 platform. Our scientific team is ready to help you select the best accessory set to make your 1x1 the most optimized platform adjustable to any application.
Limited Total Energy for tDCS (LTE-tDCS) was developed exclusively by Soterix engineers. LTE limits the voltage and power required for tDCS through the use of adaptive ramp-up stimulation and intelligent energy management for currents up to 5 mA. Soterix Medical LTE enabled devices include the most advanced transient protection in the industry, an electrode becoming temporarily disconnected, for example due to subject movement. In addition, should resistance increase to atypical levels, LTE-tDCS will automatically reduce the applied current so as to maintain a low voltage.
Soterix Medical LTE enabled devices provide additional safety margin without compromising efficacy, when stimulating susceptible subjects. Our scientific team is ready to work with you to determine optimal dose parameters and accessories.
The difference between conventional tDCS and tDCS-LTE is that conventional tDCS applies a fixed ramp slope while tDCS-LTE varies ramp intensity to limit power delivery. Soterix tDCS-LTE also limits power transients that might occur during tDCS due to sudden changes in resistance. tDCS-LTE further enhances abort-protection features already enabled on all Soterix 1x1 devices. Finally, tDCS-LTE alerts the operator when a high-power condition occurs and automatically activates LTE to reduce power consumption.
Our scientific team is ready to work with you to determine optimal dose parameters and accessories.
