1. A peripheral nerve interface, comprising
a microclip having a substantial U-shape and including an upper entry portion configured for entry of a nerve into the microclip and a lower seating portion configured for seating the nerve in the lower seating portion of the microclip;
a stretchable microelectrode array including a plurality of electrodes, wherein the stretchable microelectrode array has a proximal end portion fixed to the microclip and a portion that is moveable and dragged into the upper entry portion and then the lower seating portion of the microclip in response to the microclip being positioned on the nerve; and
an interface connected to a distal end of the stretchable microelectrode array and configured to interface with an external device for applying electrical stimulation to the nerve seated in the lower seating portion and for recording electrical characteristic of the nerve seated in the lower seating portion via the plurality of electrodes in the stretchable microelectrode array,
wherein the microclip further comprises:
flexion cut-out portions formed on each side of the lower seating portion; and
pinch protrusions protruding inward and partially separating the upper entry portion and the lower seating portion,
wherein a gap exists between the pinch protrusions that is smaller than a diameter of the nerve, and
wherein the flexion cut-out portions compress and open the microclip for entry of the nerve into the upper entry portion and for entry of the nerve from the upper entry portion into the lower seating portion.
