The Soterix 4×1 HD-tDCS adaptor converts any 2-channel tDCS stimulator into an HD-tDCS device. The 4×1 HD-tDCS adaptor is not a stand-alone stimulator, and during stimulation does not generate any current. Rather, the 4×1 HD-tDCS adaptor intelligently divides and guides current generated by a 2-channel device, converting it to HD-tDCS. The Soterix 4×1 HD-tDCS adaptor is thus an ideal solution where an existing 2-channel device is already in use.
The Soterix 4×1 HD-tDCS adaptor is fully compatible with HD-tDCS accessories and each 4×1 HD-tDCS adaptor comes with one connector cable (specify your 2-channel device, if not a Soterix 1×1 tDCS, when ordering).
Principle of operation
The 4×1 HD-tDCS adaptor interface is an accessory to an isolated 2-channel tDCS stimulator and does not function as a stand-alone electrical stimulator or generator. The 4×1 HD-tDCS adaptor device is designed to be used as an interface device between an isolated 2-channel current controlled tDCS stimulator and 5 stimulation leads; where 4 leads (colored) are connected to one output of the tDCS stimulator and the remaining lead (white) is connected to the other output of the tDCS stimulator. The output leads connect to smaller high-definition (HD) electrodes, instead of the larger sponge electrodes used in conventional 2-channel tDCS. The device operates in two modes: SCAN and PASS mode. In PASS MODE, the 4×1 HD-tDCS adaptor does not modulate the waveform of the tDCS stimulator, and acts only as a passive current divider. In SCAN mode, the device uses exclusive HD electrode impedance mapping technology to ensure proper set-up prior to stimulation.
