Abstract
A high-density microelectrode array that is flexible and stretchable and can also be implanted within living tissue is provided. The microelectrode array includes at least first and second implantable and biocompatible polymeric layers in which a plurality of patterned conductive features, including metallic contact pads, metallic traces and metallic electrodes are sandwiched therebetween. Each metallic trace is located between a metallic contact pad and a metallic electrode and has substantially rounded corners and a zigzag pattern. The latter features are provided using stent technology. The present invention also provides a method of fabricating such a flexible, stretchable, and implantable microelectrode arrays which combined micromaching technology and stent technology as well as an implantable medical device that includes the inventive microelectrode array.
