  A desktop experiment has been done to show the nonlinearity in the I-V
characteristics of an ion conducting electrochemical micro-system. Its chaotic
dynamics is being reported for the first time which has been captured by an
electronic circuit. Polyvinylidene fluoride-co-hexafluoropropene (PVdF-HFP) gel
electrolyte comprising of a combination of plasticizers (ethylene carbonate and
propylene carbonate) and salts have been prepared to study the exchange of ions
through porous poly ethylene terephthalate (PET) membranes. The nonlinearity of
this system is due to the ion exchange of the polymer gel electrolytes (PGEs)
through a porous membrane. The different regimes of spiking and non-spiking
chaotic motions are being presented. The possible applications are highlighted.
