Abstract

The WIMAGINE platform was developed as a proof of concept and first functional prototype of an implantable device for recording ECoG signals on a large number of electrodes. The designed system provides the means of recording wirelessly up to 64 ECoG channels. Two ASIC CINESIC32 ensure the amplification and digitization of the neurosignals which are then transmitted to a PC using a ZL70102 transceiver in the MICS band. An MSP430 handles the communication protocol, configures the ASICs and gives access to various sensor information. The electronics are packaged hermetically in a biocompatible titanium housing encapsulated medical grade silicone. The whole device is powered remotely over an inductive link at 13.56MHz and complies with the regulations applicable to class III AIMD.
