Abstract
Methods and systems for manufacturing a transdermal sampling and analysis device for non-invasively and transdermally obtaining biological samples from a subject and determining levels of analytes of the obtained biological samples are provided. A method of manufacturing the device may improve performance and includes forming channel structures on the lid of the device, thereby making the spacer/channel support structures physically independent and separable from the sensing electrode. Other methods of manufacturing the device may improve performance and include forming at least one of the electrodes on each of the base and the lid, and forming a recessed second spacer layer over the channel support structures, thereby separating the channel support structures and the electrode on the lid to allow a larger area of the electrode to be exposed to the biological sample.
