“…For example, an approach of exploiting reservoir computing for sensing [16], where the information about the environment is encoded in the state of the reservoir memristive computing medium, can be employed to prototype sensing-memritive devices from living fungi. A very low frequency of fungal electronic oscillators does not preclude us from considering inclusion of the oscillators in fully living or hybrid analog circuits embedded into fungal architectures [6] and future specialised circuits and processors made from living fungi functionalised with nanoparticles, as have been illustrated in prototypes of hybrid electronic devices with slime mould [68,63,47,4,20]. Electrical resistance of living substrates is used to identify their morphological and physiological state [29,56,44,40,31].…”

“…Functionalisation of living substrates aimed at increasing their sensitivity or conductivity, or imbuing them with novel properties, has been achieved before. Examples include: tuning electrical properties of plants and slime mould with nanoparticles [15,16], increasing photosynthetic properties of plants with nanoparticles [14,12] and hybridizing slime mould with conductive polymers [5,10]. An important advantage of functionalising living substrates with particles, and/or polymers, is that the substrate will remain functional, as an inanimate electronic device, even when no longer living.…”

The rapidly developing research field of organic analogue sensors aims to replace traditional semiconductors with naturally occurring materials. Photosensors, or photodetectors, change their electrical properties in response to the light levels they are exposed to. Organic photosensors can be functionalised to respond to specific wavelengths, from ultra-violet to red light. Performing cyclic voltammetry on fungal mycelium and fruiting bodies under different lighting conditions shows no appreciable response to changes in lighting condition. However, functionalising the specimen using PEDOT:PSS yields in a photosensor that produces large, instantaneous current spikes when the light conditions change. Future works would look at interfacing this organic photosensor with an appropriate digital back-end for interpreting and processing the response.

“…The application domain of the fungal electronic oscillators could be the field of unconventional computing [19], especially in the framework of organic electronics, living sensor and living computing wetware. Feasibility studies with plants [20,21], slime mould [22,23,24,25] and fungi [26,27] have shown that it is possible to develop electrical analog computing circuits either based or with these living creatures. Biological molecules such as suine microtubules have been shown to enable very fast oscillations, in the tents of MHz range [28].…”

We study long-term electrical resistance dynamics in mycelium and fruit bodies of oyster fungi P. ostreatus. A nearly homogeneous sheet of mycelium on the surface of a growth substrate exhibits trains of resistance spikes. The average width of spikes is c. 23 min and the average amplitude is c. 1 kOhm. The distance between neighbouring spikes in a train of spikes is c. 30 min. Typically there are 4-6 spikes in a train of spikes. Two types of resistance spikes trains are found in fruit bodies: low frequency and high amplitude (28 min spike width, 1.6 kΩ amplitude, 57 min distance between spikes) and high frequency and low amplitude (10 min width, 0.6 kΩ amplitude, 44 min distance between spikes). The findings could be applied in monitoring of physiological states of fungi and future development of living electronic devices and sensors.
