Tdcs Transcranial Electrical Stimulator

The most cost-effective and expandable solution for HD-tDCS / HD-tES.input:
output:The Soterix 4×1 HD-tDCS / HD-tES adaptor transforms any 2-channel Soterix Medical tDCS stimulator into an HD-tDCS / tES device. The 4×1 HD-tES adaptor is not a standalone stimulator and does not produce any current during stimulation. Rather, the 4×1 HD-tES adaptor intelligently divides and guides the current generated by a 2-channel device, converting it to HD-tES (HD-tDCS, HD-tACS, HD-tRNS, HD-tPCS, HD-tODCS). Thus, the Soterix 4×1 HD-tES adaptor is an optimal solution for situations in which an existing 2-channel Soterix Medical device is already in operation.input:
output:
The Soterix 4×1 HD-tES adaptor is fully compatible with HD-tES accessories and includes a single connector cable for connection to the 2-channel or 1x1 family of devices.input:
output:Operational principleThe 4×1 HD-tES adaptor interface is an accessory to an isolated 2-channel tDCS / tES stimulator and does not operate as a standalone electrical stimulator or generator. The 4×1 HD-tES adaptor device is intended to function as an interface between a 5 stimulation leads and an isolated 2-channel Soterix Medical current-controlled tES stimulator. Four of the leads are connected to one output of the tES stimulator, while the remaining lead is connected to the other output. In contrast to the larger sponge electrodes utilized in conventional 2-channel tES, the output leads are connected to smaller high-definition (HD) electrodes. The device functions in two modes: SCAN and PASS. In PASS MODE, the 4×1 HD-tES adaptor only functions as a passive current divider and does not modulate the waveform of the tES stimulator.
