Abstract
Described are devices, methods, and kits for non-invasively measuring glucose. In general, the devices comprise skin patches for placement on a skin surface and measurement devices for measuring glucose collected in the patches. The patches may include an adhesive material, a collection layer, an interface layer, and a sweat-permeable membrane. The sweat-permeable membrane is configured to act as a barrier to epidermal contaminants and glucose brought to the skin surface via diffusion. In this way, non-correlatable skin surface glucose will not be measured. The patches may further include components to induce a local sweat response. The measurement device typically includes a display, a processor, and a measurement mechanism. The methods typically include the steps of wiping the skin surface with a wipe containing at least one solvent for removing glucose, placing a patch on a skin surface, and measuring glucose collected in the patch. Kits comprising the patch and measurement device are also described.
