We present the first demonstration of a passive, contactless method to interrogate electrochemical impedance (EI) via a microfabricated MEMS coil. EI measurement was achieved using the principle of reflected impedance between a pair of inductively coupled coils. Ionic concentration and electrolyte temperature were wirelessly transduced from measurement electrodes connected to a microfabricated coil in a flexible thin film substrate. This technique is widely applicable for resistive transduction…

TLDR
The problem of packaging these implantable integrated sensors outside of hermetically sealed hybrid packages is described and a critical, residual aspect of the overall problem is identified: how to make a mechanically rugged and inherently noncorrodible connection between a cable and a thin film on a silicon chip.

Parylene C (poly(monochloro-p-xylylene)) is a member of a unique family of thermoplastic, crystalline polymers. Compared to other polymers, parylene films are exceptionally conformal and chemically
Electrochemical sensor for measurement of urea and creatinine in serum based on ac impedance measurement of enzyme-catalyzed polymer transformation.
TLDR
A polymer, based on poly(methylvinyl ether)/maleic anhydride modified by esterification with n-octanol, which is stable at pH 7.4 and which is transformed rapidly in response to alkaline pH changes, was linked to enzymatic reactions between urease and urea or Creatinine deiminase and creatinine to produce a disposable sensor system.
Plasma removal of Parylene C
Parylene C, an emerging material in microelectromechanical systems, is of particular interest in biomedical and lab-on-a-chip applications where stable, chemically inert surfaces are desired.
