Non-invasive transcranial direct current stimulation (tDCS) over the motor cortex is broadly investigated to modulate functional outcomes such as motor function, sleep characteristics, or pain. The most common montages that use two large electrodes (25-35 cm ) placed over the area of motor cortex and contralateral supraorbital region (M1-SO montages) require precise measurements, usually using the 10-20 EEG system, which is cumbersome in clinics and not suitable for applications by patients at home. The objective was to develop and test novel headgear allowing for reproduction of the M1-SO montage without the 10-20 EEG measurements, neuronavigation, or TMS.

Automatic M1-SO Montage Headgear for Transcranial Direct Current Stimulation (TDCS) Suitable for Home and High-Throughput In-Clinic Applications.

The adoption of transcranial Direct Current Stimulation (tDCS) is encouraged by portability and ease-of-use. However, the preparation of tDCS electrodes remains the most cumbersome and error-prone step. Here, we validate the performance of the first "dry" electrodes for tDCS. A "dry electrode" excludes 1) any saline or other electrolytes, that are prone to spread and leaving a residue; 2) any adhesive at the skin interface; or 3) any electrode preparation steps except the connection to the stimulator. The Multilayer Hydrogel Composite (MHC) dry-electrode design satisfied these criteria.
