Abstract

This paper presents a wireless system, designed for electrocortical (ECoG) neural recordings, consisting of an implantable flex-rigid ECoG array and a wireless electronic platform. The array is designed for implantation on top of the visual cortex of a Rhesus monkey. The electronic platform contains pre-amplifiers and multiplexer stages, analog-digital converters (ADCs), an inhouse developed and reconfigurable ASIC, an RF data transceiver and an inductive energy link. Our ASIC provides user-defined selection of channels (≤128), adjustable channel resolution (1-16bit), sample rate (39S/s-10kS/s), and configurable analog filters. The functionality of the whole system is successfully demonstrated by an in vitro test.
