Abstract
Devices and methods are described for improving the contact of a conductive material, for example, a hydrogel, with a sensor, for example an electrode, by means of using mechanical force to apply the conductive material to the sensor before use of the conductive material and sensor in a sampling device. The device and methods of the present invention improve the sensor response characteristics in transdermal sampling devices placed in operative contact with a skin or mucosal surface of a biological system to obtain a chemical signal associated with an analyte of interest.
