Flexible electrode for detecting changes in temperature, humidity, and sodium ion concentration in sweat

摘要

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.

1. A flexible fabric electrode sensor adapted to contact an exterior epithelium surface comprising:
a flexible fabric composite including a flexible non-conductive fabric substrate, a flexible conductive fabric intermediate layer, and a top calixarene layer formed on the intermediate layer; and a first electrode and a second electrode communicating with a controller to assess electric current across said flexible fabric composite, wherein sodium ions form a supramolecular complex with said top calixarene layer, wherein said supramolecular complex impedes charge carrier mobility and thus affects said electric current across said flexible fabric composite as assessed by said controller to provide in-situ detection of a physiological salt component in sweat or other aqueous body fluids at the exterior epithelium surface.
