Abstract
A three-dimensional (3D) microelectrode array for in vitro electrical and microfluidic interrogation of electrogenic cell constructs includes a substrate having a plurality of micro vias. A hypodermic microneedle is received within each micro via of a first subgroup of the plurality of micro vias and each has a length that exceeds the thickness of the substrate to form a hypodermic microneedle array on the top face of the substrate. Metallic traces are formed on the bottom face and interconnect the hypodermic microneedles. A culturing area is formed in the top face.
