Organic Memristive Devices and Organic Electrochemical Transistors as Promising Elements for Bio-inspired Systems

.Information processing in the brain takes place in a dense network of neurons connected through synapses. The collaborative work between these two components (Synapses and Neurons) allows basic brain functions such as learning and memorization. An efficient emulation of these computational concepts is possible only by overcoming the so-called von Neumann bottleneck, which limits the information processing capability of conventional systems. To this end, the mimicking of the neuronal architectures with silicon-based circuits, on which neuromorphic engineering is based, is accompanied by the development of new devices with neuromorphic functionalities. Several devices are reported to be suitable for this purpose among which organic-based elements are considered particularly attractive for their low fabrication costs, the easy tunability of their electronic properties and the possibility to directly interface biologic systems. This chapter is devoted to the description of some neuromorphic applications of two types of organic electronic devices based on conductive polymers.
