1. A system for detecting perspiration, the system comprising:
a sensing component comprising a resonator comprising:
a platform comprising an electronically conductive segment having a spiral shape, having pitch in a range of from about 0.1 mm to about 10 mm;
a polymeric component coating at least a portion of the electronically conductive segment; and
a microfluidic channel component defined by the platform and positioned to contact the polymeric component and
a reader to detect the resonance frequency of the resonator and positioned to be in electrical communication with the resonator.
