Abstract
Neural interfaces with the peripheral nervous system have been developed to provide a direct communication pathway between peripheral nerves and prosthetic limbs. Described herein is a method of making a microchannel integrated neural interface device comprising a plurality of hollow cylindrical electrodes in a PDMS scaffold, which can control the reinnervated muscles and interpret neurological signals. The acquired bioelectrical signals can be used for the interpretation of mind and create a neural map.
Claims8
A method of making a microchannel neural interface device comprising:
- placing a plurality of metal wires in a curable composition, wherein the curable composition comprises a polymerizable compound and wherein the metal wires have a diameter approximately equal to the diameter of a nerve axon;
- curing the curable composition to form a polymeric object having a plurality of metal wires embedded in the polymeric object;
- removing the metal wires from the polymeric object to form a plurality of microchannels within the polymeric object;
- and
- placing one or more hollow cylindrical electrodes into one or more of the microchannels, wherein each of the one or more hollow cylindrical electrodes is an elongated electrode with a hollow part of the electrode oriented coaxially with the longitudinal axis of the microchannels.
