Portable wireless electrocorticography system with a flexible microelectrodes array for epilepsy treatment

Abstract In this paper, we present a portable wireless electrocorticography (ECoG) system. It uses a high resolution 32-channel flexible ECoG electrodes array to collect electrical signals of brain activities and to stimulate the lesions. Electronic circuits are designed for signal acquisition, proc...
