HD-tDCS Systems
High-Definition transcranial Direct Current Stimulation (HD-tDCS) is a transformative technology for targeting cortical structures with weak DC currents. Unlike any other neuromodulation technique, HD-tDCS is non-invasive, targeted, and can leverage the therapeutic potential, convenience, safety, and cost-advantages of tDCS. Soterix is the exclusive manufacturer and provider of HD-tDCS technology.
The HD-tDCS systems and accessories are simple to use and provide clinicians with unparalleled flexibility in the design of targeted electrotherapy. Soterix can work closely with you in determining the optimal strategy for you needs.
There are two stimulation modalities to choose from and a range of specialized accessories. The options are designed to provide clinicians with flexibility in achieving optimal solutions. Contact Soterix to discuss your needs and to select an optimal solution.
The Soterix 4×1 Stimulator is the most advanced non-invasive neuromodulation technology. Simple to use, but providing exceptional flexibility, the Soterix 4×1 provides clinicians with previously unattainable specificity and control.
The Soterix 4×1 Stimulator is available only to approved physicians and institutions through the Soterix Medical Innovation Clinician Partnership. Contact Soterix about our Clinician Partnership Program.

HD-tDCS 4x1 Multi-Channel Stimulation Interface
The Soterix 4×1 Multi-Channel Interface converts any 2-channel tDCS stimulator into an HD-tDCS device. The 4×1 Multi-Channel is not a stand-alone stimulator, and during stimulation does not generate any current. Rather, the 4×1 Multi-Channel intelligently divides and guides current generated by a 2-channel device, converting it to HD-tDCS. The Soterix 4×1 Multi-Channel is thus an ideal solution where an existing 2-channel device is already in use.
The Soterix 4×1 Multi-Channel is fully compatible with HD-tDCS accessories and each 4×1 Multi-Channel comes with one connector cable (specify your 2-channel device, if not a Soterix 1x1 tDCS, when ordering).
HD-tDCS Accessories
Soterix provides accessories for HD-tDCS that replaces the “pads” used in conventional tDCS. In fact, HD-tDCS accessories can also be used with Soterix 1×1 tDCS systems. But only when using in combination with HD-tDCS Stimulators can the full potential of HD-tDCS, be achieved.

Note: Conventional tDCS pads cannot be used with HD-tDCS stimulators. Only approved HD-tDCS accessories can be used with HD-tDCS stimulators.
