Abstract Electrocytes has specialized function to boost up the high voltage to trap the food based on the membrane potential. Membrane potential is the difference in electric potential between membrane that is induced by the concentration differences. For high energy efficiency, membrane must have high ion selectivity. However, ion-selective membrane proteins in electrocytes are fragile and susceptible to deterioration under pH, temperature, or mechanical stress. This study focused on membrane synthesis for ultra-thin ion exchange membrane via interfacial polymerization. The next step, to increase the number of charge density in nano-membrane, the interfacial hydrogel synthesize method was novely synthesized. Using those membranes, prototype concentration cell were produced. Interestingly, those concentration cells responds to all external changes, for example, vibration, bending, temperatures. We expect that the concentration cells could extract the useful energy from any type of low-degree energies.
