Abstract
The present invention includes a flexible sensor suitable for contact with skin comprising: a nanocomposite; and a top layer; where the sensor provides in-situ detection in sweat or other aqueous body fluids at the skin surface of at least one physiological parameter selected from the group consisting of a physiological salt component, temperature, moisture, humidity, or combinations thereof. The present invention further includes a method of fabricating a flexible sensor suitable for contact with skin comprising: electrospinning at least one polyamide-producing monomer to form a non-conductive polyamide substrate; attaching at least one plurality of conductive nanoscale attachments, wherein the nanoscale attachments are selected from nanotubes, nanoparticles, or combinations thereof, to form an intermediate layer; and functionalizing the intermediate layer to form a top layer.
