WIMAGINE is a wireless low power 64-channel data acquisition system designed for Electrocorticogram (ECoG) recording. The system is based on a custom integrated circuit (ASIC) for amplification and digitization and commercial components for RF transmission. It supports the RF transmission of 32 ECoG recording channels (among 64 channels available) sampled at 1 kHz per channel with a 12-bit resolution. The RF communications use the MICS band (Medical Implant Communication Service) at 402-405 Mhz and can achieve a data rate of 480 kbps with a bit-error rate of less than 1.5 × 10-10. The device is powered wirelessly through an inductive link at 13.56 MHz able to provide 100 mW (30 mA at 3.3 V). This integration is a first step towards an implantable device for BCI (Brain Computer Interface) studies and neural prosthetics. Here, we present the platform architecture, components and the first in vivo validations. |
