Organic Memristive Devices for Neuromorphic Applications

The emulation of the hierarchical organization of the brain is nowadays considered a very promising approach for the realization of an efficient brain-machine interface and neuronal prosthesis. This bottom-up approach is possible only starting from non-classical electronic elements able to emulate synaptic functionalities such as long-term plasticity and short-term plasticity (STP). These elements then must be interfaced with technology able to mimic fundamental network properties (summation, transfer, and threshold). In this mini review, recent advances in the emulation of this hierarchical approach, obtained using a 3-terminal electronic device (organic memristive device) whose functioning is based on the redox activity of an organic thin film, are reported.
