Abstract
The invention provides a variety of novel devices, systems, and methods of utilizing mixed-ionic-electronic conductor (MIEC) materials adapted to function with an applied current or potential. The materials, as part of a circuit, are placed in contact with a part of a human or nonhuman animal body. A sodium selective membrane system utilizing the MIEC is also described.

1-19. (canceled)
A method of forming a dry electrode, comprising:
- mixing CNTs and ionic conductor and elastomer particles in an aqueous dispersion to form a CNT/ionic conductor/elastomer dispersion;
- providing a substrate comprising an electrical wire on the surface;
- depositing a conductive adhesive composition over the wire;
- applying the CNT/ionic conductor/elastomer dispersion over the conductive adhesive composition;
- and
- curing to harden the dispersion to make an MIEC connected to an electrical wire.
23-36. (canceled)
A ion sensing device, comprising:
- a working electrode and a reference electrode connected to opposite sides of a MIEC membrane wherein the reference electrode is shielded from the environment;
- and
- a voltage meter disposed between the working electrode and reference electrode.
44-51. (canceled)
A method of monitoring a chemical or biological process in an aqueous environment, comprising:
- disposing a sensor in an aqueous environment, wherein the sensor has an active surface comprising a polymeric ionic conductor coated on the active surface;
- and
- obtaining a plurality of measurements over time via the active surface in the aqueous environment.
