Propagation of electrical signals by fungi (2023)
Journal Article

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....

Marimo actuated rover systems (2022)
Journal Article

Background: The potential to directly harness photosynthesis to make actuators, biosensors and bioprocessors has been previously demonstrated in the literature. Herein, this capability has been expanded to more advanced systems — Marimo Actuated Rove... Read More about Marimo actuated rover systems.

Stimulating fungi Pleurotus ostreatus with hydrocortisone (2021)
Journal Article

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)
Journal Article

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

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.

Beyond Markov chains, towards adaptive memristor network-based music generation (2013)
Presentation / Conference Contribution

We undertook a study of the use of a memristor network for music generation, making use of the memristor's memory to go beyond the Markov hypothesis. Seed transition matrices are created and populated using memristor equations, and which are shown to...

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.

Neuromorphic computing with memristors: Preliminary experimental results (2011)
Presentation / Conference Contribution

Individual memristors have been observed demonstrating neuron-like spiking patterns. It has been shown
elsewhere that memristors provide superior modelling for neurons then the Hodgkin-Huxley model. Due to
these results we expect memristors to be e... Read More about Neuromorphic computing with memristors: Preliminary experimental results.

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

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.

Chemical tessellations - Results of binary and tertiary reactions between metal ions and ferricyanide or ferrocyanide loaded gels (2010)
Journal Article

In our recent letter [de Lacy Costello et al., 2009] we described the formation of spontaneous complex tessellations of the plane constructed in simple chemical reactions between drops of metal salts and ferricyanide or ferrocyanide loaded gels. In t... Read More about Chemical tessellations - Results of binary and tertiary reactions between metal ions and ferricyanide or ferrocyanide loaded gels.

Reaction-diffusion controllers for robots (2009)
Book Chapter

Excitable systems, particularly spatially extended media, exhibit a wide variety of travelling patterns and different modes of interaction. The Belousov-Zhabo-tinsky [1] (BZ) reaction is the most well known and extensively studied example of non-line... Read More about Reaction-diffusion controllers for robots.

Experimental validation of binary collisions between wave fragments in the photosensitive Belousov–Zhabotinsky reaction (2009)
Journal Article

Using the examples of an excitable chemical system (the Belousov–Zhabotinsky medium) and plasmodium of Physarum polycephalum we show that universal computation in a geometrically unconstrained medium is only possible when resources (excitability or c...

Spiral formation and degeneration in heterogeneous excitable media (2009)
Journal Article

Spontaneous spiral formation occurs when an excitation wave is input to a heterogeneous network of low- and high-light-intensity cells projected onto a light-sensitive Belousov-Zhabotinsky reaction. The range of network conditions where spirals form... Read More about Spiral formation and degeneration in heterogeneous excitable media.

Implementation of glider guns in the light-sensitive Belousov-Zhabotinsky medium (2009)
Journal Article

In cellular automata models a glider gun is an oscillating pattern of nonquiescent states that periodically emits traveling localizations (gliders). The glider streams can be combined to construct functionally complete systems of logical gates and th...

Chemical tessellations (2009)
Journal Article

We report a simple set of chemical reactions based on the reaction of a range of metal salts with potassium ferricyanide loaded gels that spontaneously produce complex and colorful tessellations of the plane. These reactions provide a great resource... Read More about Chemical tessellations.
