About this Research Topic
Further development of memristors, including conventional applications, is necessary from the point of view of the current market need for new nanoelectronic circuit architectures. Memristor circuits working on the edge of chaos can exhibit very complex behaviour. The application of a new excitable medium in investigations to detect the global motion of excitable waves and transferring this to the analysis of more complex systems such as brain networks and social networks, is particularly challenging. Especially emergent behaviour suggests a way forward in artificial intelligent systems by taking inspiration from different complex systems in biology and chemistry. This will in turn aid implementations for different model parameters and boundary conditions in order to draw a complete picture for the generation of excitable waves and pattern phenomena.
The topics of interest for this Research Topic article collection include (but are not limited to):
- Memristor analysis - certain systems have the ability to self-organize into spatially structured states from initially unstructured or spatially homogenous states. This behaviour takes place all over the place, physics in chemistry in biology in social science etc. Discussion of the basic ingredient that are necessary for these processes to occur.
- Memristor modelling - there is still a wide gap between the bioinspired systems and the neuromorphic circuit’s connectivity. Modelling of several interesting features among which the possibility of modulating the weights of hard connections (established between local input and output) by the voltage applied on the electrolyte seems particularly interesting for neuromorphic applications.
- Memristor computing - the high number of neuronal connections in the biological brain allows an efficient parallel computing and originate global mechanisms that modulate neural processing.
- Memristor fabrication - accurate experimental and computational characterization of the complex dynamics of a locally active memristor fabricated in house.
- Memristor circuits and systems design - the experimental and theoretical investigations supporting the design and fabrication of electrical circuits chosen from two distinct applications - spatio-temporal pattern recognition and digital logic - and based upon the locally-active threshold switching behaviour of memristor device.
- Memristor devices- the two-terminal nature of memristor devices and their ability to change conductance when stimulated with voltage pulses and evolve into states based on input history make them almost ideal electronic analogues of biological synapses.
