Living organisms are based on the mass flux that induces various biological reactions using nanosized asymmetric ion channels as highly selectivity. However, it is the aggressive challenge to use these channels for artificial membranes because these are fragile and susceptible to deterioration under pH, temperature, mechanical stress, etc. This study, for the first time, synthesized a virus nanochannel-embedded thin film composite membrane. This membrane shows the extremely high ion selectively as well as low resistance. This property can be used to extract various multi-energies, for example, external pressure, water dropping, temperature difference, etc. This electricity results from the entropy gradient between membrane like electric eels.
