The most economical and scalable solution for HD-tDCS / HD-tES.
The Soterix 4×1 HD-tDCS / HD-tES adaptor converts any 2-channel Soterix Medical tDCS stimulator into an HD-tDCS / tES device. The 4×1 HD-tES adaptor is not a stand-alone stimulator, and during stimulation does not generate any current. Rather, the 4×1 HD-tES adaptor intelligently divides and guides current generated by a 2-channel device, converting it to HD-tES (HD-tDCS, HD-tACS, HD-tRNS, HD-tPCS, HD-tODCS). The Soterix 4×1 HD-tES adaptor is thus an ideal solution where an existing 2-channel Soterix Medical device is already in use.
The Soterix 4×1 HD-tES adaptor is fully compatible with HD-tES accessories and each 4×1 HD-tES adaptor comes with one connector cable to connect to the 2-channel or the 1x1 family of devices.
Principle of operation
The 4×1 HD-tES adaptor interface is an accessory to an isolated 2-channel tDCS / tES stimulator and does not function as a stand-alone electrical stimulator or generator. The 4×1 HD-tES adaptor device is designed to be used as an interface device between an isolated 2-channel Soterix Medical current controlled tES stimulator and 5 stimulation leads; where 4 leads are connected to one output of the tES stimulator and the remaining lead is connected to the other output of the tES stimulator. The output leads connect to smaller high-definition (HD) electrodes, instead of the larger sponge electrodes used in conventional 2-channel tES. The device operates in two modes: SCAN and PASS mode. In PASS MODE, the 4×1 HD-tES adaptor does not modulate the waveform of the tES stimulator, and acts only as a passive current divider.
