Neural interfaces allow the establishment of connections between the nervous system and external electronics, and hold great potential in both the clinic and basic research. The peripheral nervous system is a particularly attractive site to position an interface. Nerves are easy to access surgically and action potentials carried by them correlate well with activity at their target. Current nerve interfaces are however unstable in long-term implantation scenarios due to the development of a foreign body reaction.
In order to avoid this foreign body reaction, we are testing low-stiffness materials as potential components for neural interface manufacture. Work in our lab has shown that in the rodent CNS this rejection process is reduced if implant stiffness is matched to that of the tissue. My current work aims to determine whether this also holds true for the peripheral nervous system, and to exploit this finding by developing a “soft” nerve prosthesis.
