Research Abstract

A novel subdural electrode array guided by a shape-memory-alloy thin wire have been developed for minimally-invasive ECoG measurement. The measured electric characteristics provided the evidences that the electrodes are suitable for ECoG measurement. The utility for ECoG measurement and the invasiveness of procedure were verified with the animal tests. An ASIC for amplification of measured ECoG signal was fabricated, and provided the desired function.
