1. A device comprising:
a flexible substrate;
a flexible integrated circuit within the flexible substrate, the integrated circuit having at least one input electrode positioned on a surface of the flexible substrate; and
an aerosol-jet printed conductive ink layer disposed on the surface of the flexible substrate, the aerosol jet printed conductive ink layer having a pattern that includes a first set of fingers interdigitated with a second set of fingers, the aerosol-jet printed conductive ink layer in contact with the at least one input electrode.
