Subdural Electrocorticogram Measurement with a Minimally-Invasive Procedure Using an SMA-Manipulated Microelectrode Array
We propose a subdural electrode array guided by a 0.3mm-diamter shape memory alloy guidewire for a minimally-invasive method of electrocorticogram recording. The measured electric characteristics showed that the proposed electrodes are compatible with the application of electrocorticogram recording. Somatosensory evoked potential was measured by the proposed method in the animal test in vivo. The results confirmed that the proposed electrode array is available for the electrocorticogram recording under a minimally-invasive surgery.
