摘要：
Disclosed are biocompatible multi-electrode devices capable of being implanted in sensitive tissue, such as the brain, and methods for fabricating such arrays. The disclosed arrays can be implanted in living biological tissue with a single needle insertion. The devices can include linear arrays with contacts along an edge, linear arrays with multiple electrodes per opening in a parylene support layer, multi-thread electrode arrays, tree-like electrode arrays, and combinations thereof. In an embodiment, a compliant electrode apparatus can comprise a biocompatible and bio-implantable compliant dielectric having a top edge defined by a top and a side along a length of the dielectric, insulated electrical traces oriented along the length of the dielectric, and electrode contacts coupled to the traces and situated on the side along the length of the dielectric, wherein an exposed portion of a respective electrode contact protrudes beyond the top edge of the dielectric.
