BioFunctional IntraNeural Electrodes

Project Details


BioFunctional IntraNeural Electrodes : In BioFINE we will develop flexible intraneural multielectrode arrays, capable of interfacing
peripheral nerves e.g. to transfer input/output signals from bionic limbs. Specifically, we address the challenge of long term tissue integration and chronic stability, by addressing three aspects of biocompatibility: 1) We develop novel fabrication methods allowing the intraneural interface to be defined at even finer resolution than before; 2) we explore functionalizations which will control the
tissue response by combined surface anchored and surface eluted agents; 3) we address structural biocompatibility on a system level by engineering novel implantable interconnects which reduced tethering forces and improve prospects for high channel count interfaces.
Fine-tuned bioactivity will safe-guard surrounding neural tissue in the initial stages of healing, and implants of sub-cellular dimensions and tissue compatible biomechanics, will safe-guard tissue healthy in the longer term. The combined approach will offer optimal conditions to bridge the gap from electrode to neuron and generate a long term functional peripheral nerve interface. Indeed, each of the three technological advancements would on their own have substantial impact on neurotechnology, reaching far beyond intraneural interfaces.
