MULTI-SITE ELECTRODE ARRAYS AND METHODS OF MAKING THE SAME

摘要

A multi-site electrode array (100) can include a microneedle array and a set of electrically active sites (115). The microneedle array includes a plurality of microneedles (105) supported on a base substrate (110). The set of electrically active sites (115) can be arranged at and/or near the tip of each microneedle (105), and in many cases along a shaft of the microneedles. Further, at least a portion of the active sites (115) can be independently electrically addressable such that a remaining portion of the active sites (115) are optionally electrically shunted together. In some cases all of the active sites (115) are independently electrically addressable
