Abstract
A microneedle electrode array is disclosed. The microneedle electrode array can include a substrate configured to stretch or move between a first state and a second state. A plurality of microneedles can extend outwardly from the substrate and include a base. A plurality of electrical interconnects is extended from the plurality of microneedles.

A method of making a microneedle electrode array, comprising:
- forming a plurality of cavities having a microneedle shape on a surface of a mold substrate;
- filling the plurality of cavities and the surface of the mold substrate with a polymeric material to form a plurality of microneedles;
- patterning the polymeric material on the surface of the mold substrate to form a pattern of a plurality of interconnects on the surface of the mold substrate that are connected with and extended from the plurality of microneedles;
- attaching the pattern of the plurality of interconnects and the plurality of microneedles to an array substrate;
- removing the mold substrate to expose the plurality of microneedles and the pattern of the plurality of interconnects as attached to the array substrate;
- and
- disposing an electrically conductive material onto an exposed surface of the plurality of microneedles and the pattern of the plurality of interconnects.

A method for treating a three-dimensional structure, comprising:
- moving a surface portion of the three-dimensional structure into a deformable material;
- treating the surface portion disposed into the deformable material by removing material from the surface portion or applying material onto the surface portion;
- and
- removing the treated surface of the three-dimensional structure from the deformable material.
