Electrochemical System with Memimpedance Properties

An electrochemical system based on a pH-switchable polymer-modified electrode was designed to demonstrate memory properties. The pH changes in the system were produced electrochemically in situ upon electrochemical reduction or oxidation of H2O2. Depending on the direction of the current, different pH changes were achieved and the modified electrode was switched between higher or lower resistance and capacitance. In the absence of the current the electrode preserved the last resistance and capacitance values, thus demonstrating properties of memristor and memcapacitor simultaneously (memimpedance). The switchable interface between the modified electrode and solution potentially allows functional integration between the electrochemical memimpedance device and biomolecular systems processing chemical signals.
