1) General electrochemical applications are precise industrial fluidic measurements
and differential fluidic meters in research and laboratory usage, detectors of weak
(non-)electromagnetic emissions by analysing electrochemical changes in fluids.
The device is suitable for the analysis of differential electrochemical properties of
samples exposed by non-chemical, non-temperature, non-acoustic, non-mechanical
and non-electromagnetic factors.
2) General electrophysiological applications are plant, organic tissue and
microbiological measurements for phytosensing and biosensing usage, e.g.
monitoring plant physiology and electrophysiology, analysis of bio-potentials and
tissue conductivity, bio-sensors based on fermentation, sedimentation, gas
production (or degassing), metabolic production or any other processes that change
concentration and mobility of ions. The MU EIS system is designed for long-term
monitoring of biological samples, e.g. for quality control purposes or for the analysis
of biochemical reactions.
3) Analysis and measurements of weak interactions, in particular in research of
certain quantum phenomena appearing in macroscopic systems. Examples are the
proton tunneling effect and self-ionization of water based on quantum fluctuation of
E-field. These quantum effects on the micro-level between water molecules, ions
and protons, causes changes of fluidic parameters on the macro-level, which can be
in turn measured as changes of e.g. impedance. The device allows statistically
significant measurements of these effects with the standard EIS method.
