Deliverables

Report on novel cortical µECoG and intracortical technologies

Report on the performance of non-multiplexed µECoG surface probes and intracortical devices based on graphene field-effect transistors and PEDOT:PSS organic-electrochemical transistors and electrodes. Benchmarking with competing technologies (metal electrode arrays).

System integration of first multiplexed neural interfaces with digital output

Discrete electronics, ASIC, data management and packaging developments to integrate the developed small area neural interfaces with frequency-domain multiple access (FDMA) multiplexing technique of up to 8x8 recording sites into electrophysiological recording systems. This first ASIC also includes the A/D conversion of all the multiplexed channels but not any digital post-processing oriented to data compression. This deliverable improves the initial description of D2.1 by introducing a novel continuous-time multiplexing capability, whose number of channels can be up-scaled in the subsequent deliverables.
