Abstract
A device for monitoring an analyte is described, which includes (a) a support having an interior surface and an exterior surface; (b) a substrate connected to the interior surface of the support; (c) a spacer connected to the interior surface of the support and encompassing the substrate; and (d) a first membrane, permeable to the analyte, having an interior surface and an exterior surface, the interior surface being connected to the spacer. A chamber that encloses the substrate is defined by the interior surface of the support, the spacer, and the interior surface of the first membrane. The spacer exceeds the substrate in elevation such that a void volume exists between the interior surface of the first membrane and the substrate. A method of using the device for the transdermal monitoring of an analyte is also described.
