Soterix Medical 1x1 Platforms

The state-of-the-art modular and fully compatible series of non-invasive electrical brain stimulation devices and accessories. The most precise and reproducible systems, customized to your clinical trial.

Better neuromodulation starts with better stimulators

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 five stimulator devices, upgradable adaptors, and state-of-the-art accessories customizable to your needs.

  • Transcranial Direct Current Stimulation (1x1 tDCS) for industry standard control and safety
  • tDCS with Limited Total Energy (1x1 tDCS-LTE) unique safety feature for susceptible populations
  • Transcranial Alternating Current Stimulation (1x1 tACS) for unmatched precision in AC
  • Transcranial Electrical Stimulation (1x1 tES) for versatile solution in a single system including tDCS, tPCS, tACS, and tRNS.
  • 1x1 Clinical Trials (1x1-CT) for the most advanced solution for true double-blind clinical trials in tDCS, tPCS, tACS, and tRNS.
  • Designed for Neuromodulation. Customized for your trial.

    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.

    Four design principles of Open-Panel™ Device Interfaces

    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.

    Open-Panel™ Reproducibility Advantage

    No drop down menus.
    No hidden setting.

    Avoid confusion and mistakes. Save time. 1x1 devices can be programmed in seconds with simple switches and controls.

    No external computer.
    All devices stand alone.

    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.

    Elevated panels.
    Backlit displays.

    Easy to read displays, even at a distance and even in reduced light conditions, means you always can monitor stimulation status.

    Optimized devices.
    Customized interfaces.

    In advanced neuromodulation, one size does not fit all. Display and control items are minimized to what you need. Clarity and simplicity without compromise.

    Open-Panel™ Safety Advantage

    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.

    Simple to use


    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.

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

    Expert support and target modeling

    Researchers and clinicians choose Soterix Medical products knowing that they are backed by the most experienced neuromodulation engineers, regulatory staff, and clinical trial design consultants. Soterix Medical was founded with one mission: to advance the science of neuromodulation. We are your partner every step of the way.

    Only HDexplore for tDCS allows you to simulate any tDCS montage, not just a sub-set, on a range of standard head or custom loaded head models. But consistent with our Open-Panel™ design principles , HDexplore software is stand-alone from hardware, available when you need it and not when you don't.

    State-of-the-art software driven control and modeling

    Soterix Medical Neurotargeting Software allows the user to stimulate any transcranial Electrical Stimulation montage. You decide the number of electrodes and current intensity. Simply position the electrodes relative to the EEG 10/10 (70+ scalp locations) system or a dense concentric system (300+ scalp locations), thereby allowing inclusion of intermediate scalp or neck positions. Use our standard head library or import your own anatomical scans. Arbitrary electrode montages and head models: exclusively from Soterix Medical Neurotargeting Software.
