Living fungal mycelium networks are proven to have properties of memristors, capacitors and various sensors. To further progress our designs in fungal electronics we need to evaluate how electrical signals can be propagated through mycelium networks....

Fungi cells can sense extracellular signals via reception, transduction, and response mechanisms, allowing them to communicate with their host and adapt to their environment. They feature effective regulatory protein expressions that enhance and regu... Read More about Stimulating fungi Pleurotus ostreatus with hydrocortisone.

Neuromorphic liquid marbles with aqueous carbon nanotube cores (2019)

Neuromorphic computing devices attempt to emulate features of biological nervous systems through mimicking the properties of synapses, towards implementing the emergent properties of their counterparts, such as learning. Inspired by recent advances i... Read More about Neuromorphic liquid marbles with aqueous carbon nanotube cores.

Observation, characterization and modeling of memristor current spikes (2013)
Journal Article
Gale, E., de Lacy Costello, B., & Adamatzky, A. (2013). Observation, characterization and modeling of memristor current spikes. https://doi.org/10.12785/amis/070418

Memristors have been compared to neurons (usually specifically the synapses) since 1976 but no experimental evidence has been offered for support for this position. Here we highlight that memristors naturally form fast-response, highly reproducible a... Read More about Observation, characterization and modeling of memristor current spikes.

Logical and arithmetic circuits in Belousov-Zhabotinsky encapsulated disks (2011)
Journal Article

Excitation waves on a subexcitable Belousov-Zhabotinsky (BZ) substrate can be manipulated by chemical variations in the substrate and by interactions with other waves. Symbolic assignment and interpretation of wave dynamics can be used to perform log... Read More about Logical and arithmetic circuits in Belousov-Zhabotinsky encapsulated disks.

Towards constructing one-bit binary adder in excitable chemical medium (2011)

The light-sensitive modification (ruthenium catalysed) of the Belousov-Zhabotinsky reaction exhibits various excitability regimes depending on the level of illumination. Within a narrow range of applied illumination levels the medium is in a sub-exci... Read More about Towards constructing one-bit binary adder in excitable chemical medium.
