Impedance and DBS performance of the elastomer electrode. A. Impedance spectrum of the elastomer electrode for neural stimulation. A thin layer of gold is sputtered on the side of the conductive elastomer core to provide better conductivity. Very low impedance is recorded on the polymer electrode to prove the neural stimulation capability. B. STN DBS with the soft wire evoked a strong LFP in the ipsilateral motor cortex recorded by a ground screw EEG. Stars denote the electrical stimulation artifacts.
