“…[179,180] This could permit the design of mycelium composites for optical, tactile, and chemical sensors; storage devices; signal processors, and decision-making tools. [181] Adamatzky [182] has suggested that mycelium decision-making tools could convert environmental stimuli received through the fruiting body into electrical signals and the computation would be conducted within the mycelium network itself. There is also an interest to use mycelium for the next-generation of monolithic buildings that can self-grow and self-repair using natural environmental adaptation mechanisms.…”

The socio‐economic struggles in Africa are partly attributed to the low productivity of the agricultural sector. The Sustainable Development Goals Centre for Africa (SDGC/A) and the African Development Bank Group (AfDBG) both agree that the continent needs sustainable interventions to boost agricultural productivity, employment, and income. In this regard, mycelium composite production can present one potential solution. The added value to agricultural waste used to produce mycelium composites can generate additional revenue for farmers, serving as an incentive to increase agricultural productivity. Furthermore, the establishment of mycelium composite start‐ups can increase employment and income, especially for women and the youth. Mycelium composites can also aid in mitigating environmental and health challenges caused by some of the current waste management practices in Africa. This review offers valuable insights into the potential use of mycelium composites as a sustainable alternative for Africa. It explores the potential use of locally accessible resources, the potential applications for the composites in Africa, and the potential challenges that may arise with this technology. It further assesses the potential contribution of this technology to sustainable development in Africa in line with the Sustainable Development Goals (SDGs) set by the United Nations (UN).

“…Second, we can prototype neuromorphic circuits with kombucha mats. There is a high likelihood of kombucha mats exhibiting memristive properties (similar to memristive properties of slime mould [51] and fungi [52]). The memristive properties would further imply [53, 54, 55, 56] that it is possible to implement learning, memory and construct synaptic connections in the zoogleal mats.…”

A kombucha is a sugared tea fermented by a symbiotic community of over twenty species of bacteria and yeasts. The community produces and inhabits cellulosic gelatinous zoogleal mats. We studied electrical activity of the kombucha mats using pairs of differential electrodes. We discovered that the mats produce action like spikes of electrical potential. The spikes are often grouped in the trains of spikes. Characteristics of the spikes and trains of spikes are presented. We demonstrated that electrical responses of kombucha mats to chemical, electrical and optical stimulation are distinctive and therefore the mats can be used as sensors, or even unconventional computing devices.

In this concept article, we review recent works on the use of biologically-derived materials, including biomolecules, hybrid biomolecular composites, and natural tissues for achieving stimuli-responsiveness, adaptability, and memory storage for potential neuromorphic computing applications. Unlike solid-state materials, bioderived platforms are often intrinsically modular, including possessing the ability to leverage the diversity of naturally multifunctional biomolecules, cornerstones in biological transduction, signaling, and learning. The primary neuromorphic functionality of bioderived systems considered here is memory resistance, as obtained through combinations of resistive switching, activity-dependent plasticity, and memory storage. In some cases, these capabilities are achieved in bio-derived systems by closely emulating the structure, function, or signaling mechanisms found in living neurons. Our review considers bioderived systems that span multiple length scales and levels of hierarchical complexity: from single-molecule enabled devices to intact tissues, interrogated either in vitro or in vivo on living organisms. Through this exercise, we offer our perspective on research opportunities in the development and use of synapse- and neuron-inspired bioderived systems, including the prospect of biocompatible, and even tissue-like, neuromorphic materials to smartly monitor and treat injury and disease, deliver therapeutics, and interpret neural activity. These capabilities could unlock a new generation of smart, adaptable bioderived composites that autonomously report, learn (i.e., classify, forecast), compute, and actuate in the direct vicinity of living cells and tissues, i.e. at the edge of biology.
