1. A method for manufacturing analyte sensing microneedles, the method comprising:
removing material from needle bodies to form sharp tips of microneedles; and
forming at least one layer along at least one of the sharp tips of a respective one of the microneedles, which has an electrically conductive inner portion and an electrically insulating material surrounding the electrically conductive inner portion, wherein the insulating material defines an outer skin-contacting surface of the respective microneedles and exposes the at least one layer is configured to detect at least one analyte in interstitial fluid when the microneedles are positioned within a user's skin.
