The Soterix Medical 1×1 transcranial Electrical Stimulation (1×1-tES) device is the most sophisticated and precise stimulator ever designed for tDCS, tACS, tPCS, and tRNS. The 1×1 tES represents a decade of biomedical and industrial design to create a device that combines unmatched flexibility, reliability, and easy-of-use through unique Soterix Medical features and the Open-Panel™ interface.


The Complete System for tES

Complete Waveforms

The Soterix Medical 1×1 tES device provides reproduction of tDCS, tACS, tPCS, and tRNS protocols used in clinical trials. The 1×1 tES is thus a single device that be programmed to provide a broad range waveforms. For any tES waveform, a matched sham waveform is enabled simply by engaging the sham switch. The Soterix Medical 1×1 tES is thus the best option for research labs that want the flexibility to test across tES waveforms with the established reliability and precision of the Soterix Medical 1×1 platform.

Complete Accessories

Compatibility with the state-of-the-art 1×1 platform accessories provides even more flexibility including

  • The only pad electrodes designed for tES and industry standard head-gear.
  • The ability to simply upgrade to multi-channel pad stimulation (e.g. 2×1 or 2×2) using the economical breakout boxes.
  • Upgrade to HD-tDCS using the 4×1 adaptor and provide any waveforms with 4×1 targeting
  • Use Soterix Medical Neurotargeting software to design and prove brain targeted montaged

Soterix Medical Quality

The Soterix Medical brand represents the highest quality and standards in tES because each device is designed based on the latest science and biomedical engineering. The Open-Panel™ interface provides the simplest most-intuitive interface while embedded electronics work over-time to ensure precision and tolerability, even under unexpected conditions. Advancing the practice of tDCS requires devices and protocols integrating the latest advances in technology and science. Soterix Medical was founded to support this effort and continues to provide unparalleled support to every user – with devices and accessories that incorporate exclusive features for rigorous trial design, tolerated procedures, and reproducible protocols. Introduced in 2014, the 1×1-tES stimulator represents the most sophisticated stimulator ever built for tES while building on the validated 1×1 platform.


Industry Leading Precision and Control

The most essential feature of a programmable tES device is precision and control of current output. The Soterix Medical 1×1 tES uses state-of-the-art electrical and biomedical engineering design to provide the highest temporal and intensity precision of any tES stimulation device: Adjustable output current in increments of 10 µA, 12 bit D/A, variable sampling time for accurate reconstruction of higher frequencies – 71 µs resolution for 200Hz signals.

Control means that across physiological loads (e.g. head size and electrode impedance), the target current is maintained. Soterix Medical is the only company that provides an independent current meter, the “True-Current” feature, which demonstrates reliability continuously during use. Researchers and clinicians used the Soterix Medical 1×1 tES when the highest quality stimulation signal is required.

Simple to use Open-Panel™ controls

The Soterix Medical 1×1 platform devices stand out for their simple controls and interfaces. Program the device precisely in seconds, with no complex drop-down menu, hidden settings, or need to establish a wireless connection with an external computer. The device program is clearly visible through the knob settings and backlit features like SmartScan™ and TrueCurrent™. Waveform and frequency control knobs and displays make programming straightforward. With Soterix Medical Open-Panel™, simplicity and clarity means that set-up time and potential programming errors are reduced.
