Interfacing Physarum polycephalum with organic memristors

Since their prediction, memristive devices revolutionized the world of computing and nowadays they have been widely considered as promising candidate for mimicking synapses. In particular, organic-based memristors allow the construction of circuits capable of learning. Physarum Polycephalum slime mold is well suited for the implementation of the functional properties of smart living systems into electronic devices. Physarum has memory patterns that can be associated to learning, generally considered a feature of more complex species. Here we presents the characteristics of an hybrid memristor developed by interfacingpoly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonate), (PEDOT: PSS), with Physarum Polycephalum (PP). The device has memristive features resulting by electrochemical changes occurring into the polymer upon application of anodic potentials across the semiconducting PEDOT: PSS channel.
