1. A device, comprising:
- a backing layer;
an adhesive layer comprising a plurality of nanofibers attached to the backing layer to couple the device to a patient tissue; and
two or more electrical contacts positioned within or beneath the adhesive layer, wherein the two or more electrical contacts are capable of conducting a current through the adhesive layer or through the patient tissue to provide a signal related to an adhesive state of the adhesive layer.

Abstract
Nanofiber adhesives and their uses with device, such as medical devices, are described. In one embodiment, a nanofiber adhesive layer may be disposed on a surface of a medical device, such as a backing layer of a sensor, for adhesion to a substrate. The nanofiber adhesive layer may allow durable adhesion to the substrate. Other described features may include materials and methods to determine the attachment of the medical device to a patient by determining the adhesive state of the adhesive layer.
