  • an adhesive material;

    a collection layer for collecting sweat;

    a sweat-permeable membrane configured to act as a barrier to epidermal contaminants and as a barrier to glucose brought to a skin surface via diffusion when the skin patch is in contact with the skin surface, wherein the sweat-permeable membrane comprises a liquid polymer that cures when exposed to oxygen and that is adapted to leave openings over sweat gland pores on the skin surface upon curing;

    a detector configured to detect nanogram quantities of glucose in sweat; and
