The world of computing is undergoing a quiet revolution that sounds almost fantastical: machines built with mushrooms and the living networks of fungi. In the wake of growing concerns about energy use, e-waste, and the environmental footprint of modern devices, researchers are asking a provocative question: could the future of computing be fungal? The phrase may sound like a page from a sci‑fi thriller, yet it sits at the edge of real science. In 2025, a landmark study from Ohio State University argued that “The Future Of Computing Could Be Fungal,” opening a new chapter in bioelectronics, sustainable tech, and the race to rethink how information is stored and processed.
For Revuvio readers, this topic blends curiosity with a practical concern: can biology help us build greener, smarter machines? The short answer is that we’re not there yet, but the trajectory is compelling. Fungi offer a natural blueprint for low‑power information processing, self‑healing materials, and biodegradable components. While today’s mushroom computers remain experiments housed in lab benches rather than living rooms, their progress helps us imagine a future where computing is closer to nature—quiet, efficient, and less wasteful. Below, we explore the science, the potential, the challenges, and the real timelines that could bring life to a new generation of eco‑friendly electronics.
The science behind fungal computing
At the heart of this concept is mycelium, the root‑like network through which fungi communicate, absorb nutrients, and coordinate growth. Mycelium forms a vast, decentralized “wood wide web” that some researchers compare to a biological internet, where chemical signals guide collective responses across a colony. If scientists can harness the electrical aspects of this network, they may create computing elements that function like memory and logic units without conventional silicon components.
What is a memristor, and why does it matter for fungi?
A memristor is a circuit element that remembers its history of electrical states. In traditional hardware, memory sits separate from processing. Some fungal researchers propose that mycelial networks could act as organic memristors, storing information through enduring changes in electrical conductance. In practice, researchers at OSU and collaborators conducted experiments where shiitake mushrooms were exposed to varying voltages, and the resulting electrical states demonstrated switchable memory behavior. The findings showed switching speeds in the thousands of signals per second range with notable accuracy, offering a glimpse into how a fungal computer might retain a bit of data without solid‑state memory.
Wood wide web and information flow
The wood wide web isn’t just metaphor; it’s a real ecological network that broadcasts signals about moisture, nutrients, and stress among fungal colonies and their plant partners. Translating this natural communication into computing requires a careful design so that electrical signals can be generated, routed, and read in a predictable way. The challenge is not merely to mimic biology, but to convert biology’s energy‑efficient signaling into reliable digital functions. If successful, such designs could yield computing substrates that are self‑assembling, adaptable, and capable of local processing with far lower energy footprints than conventional chips.
How a mushroom computer could work
To envision practical mushroom computing, it helps to picture three key components: a living bioelectronic medium (the mycelium), a method for inserting and reading electrical signals, and an architecture that can interpret those signals as information. The OSU work demonstrates that fungi can behave like organic memristors, meaning they can “remember” previous electrical states and influence future responses. This memory capability is essential for storage and for implementing basic computational functions.
Design concepts and potential architectures
One concept is to embed mycelial networks in a matrix with electrodes that inject voltages, allowing the fungi to alter their conductive properties in a controlled way. The evolving architecture could resemble a cross‑point grid where each mycelium junction acts as a programmable switch or a tiny memory bit. Another idea involves layering fungal cultures with natural or synthetic electrolytes to create soft, flexible computing fabrics that can be woven into wearables or sensor skins. The advantage is clear: such systems could be more forgiving to mechanical stress and could be produced with fewer rare minerals than silicon chips require.
What the lab results show today
In controlled tests, shiitake mushrooms connected to simple electrode assemblies demonstrated memristive behavior. When researchers sent ramped electrical pulses, the fungi showed non‑volatile responses—changing their state in a way that persisted after the stimulus ended. The OSU experiments reported data storage in RAM‑like modes with rapid state changes and reasonably high fidelity. While these results are foundational, they also reveal the hurdles: environmental sensitivity, variability across organisms, and the need to scale from single‑mushroom experiments to robust, multi‑node networks.
Why fungal computing matters now
The appeal of mushroom‑based electronics goes beyond novelty. The environmental and practical benefits are compelling when you consider the lifecycle of devices we use every day. Fungi offer a path toward more sustainable energy use, easier recycling, and potentially novel ways to monitor and interact with our environment. In a world where electronics dominate daily life, research into bio‑based computing aligns with broader goals—from reducing e‑waste to extending the lifespan of devices through self‑repairing materials and biodegradable components.
Eco‑friendly by design
Fungal materials are inexpensive to cultivate at scale and naturally biodegradable, which could dramatically reduce end‑of‑life waste compared with conventional plastics and metals used in electronics. If mushroom‑based components can be manufactured with less energy input and without rare earth minerals, the environmental footprint of our digital world could shrink substantially. It’s not just about making devices that run on fungi; it’s about rethinking the entire supply chain, from raw materials to disposal, to be more harmonious with ecological limits.
Energy efficiency and resilience
Biological systems are optimized over eons for energy efficiency. In theory, fungal computing could deliver memory and processing with far lower power consumption than modern transistors when used for niche tasks such as sensing, edge computing, or low‑power inference. Imagine sensors deployed in remote ecosystems or in smart agricultural settings that operate for years on minimal energy, powered by ambient bioelectrical phenomena or tiny, biofriendly energy harvesters. That kind of resilience could dramatically reduce the frequency of battery replacements and the associated environmental impact.
Realistic timelines, progress, and challenges
While the idea is captivating, it’s important to separate the science from hype. The current generation of mushroom computers cannot yet rival silicon in speed or density. The OSU demonstrations show intriguing proof of concept, not replacement capability. Here are the key realities shaping timelines and adoption prospects:
Conventional memristors in today’s electronics can switch states much faster than the best fungal implementations observed so far. Fungal memristors might be slower and more variable, which is typical of living systems. - Scalability: Moving from a few mushrooms on a lab bench to a scalable, manufacturable system is nontrivial. Uniform behavior across large arrays of living organisms is a major hurdle.
- Stability and control: Living materials react to temperature, humidity, and contamination. Creating predictable, repeatable behavior requires careful environmental control and robust design principles.
- Integration with silicon: For practical use, bioelectronic components must interface reliably with existing digital logic and memory stacks, which demands new standards, connectors, and error‑correction strategies.
- Regulatory and safety considerations: If living tissues are used in consumer electronics or medical devices, safety and regulatory compliance become additional layers of complexity to navigate.
Experts emphasize a phased approach: first, develop fungal components for specialized, low‑power tasks such as environmental sensing or on‑device data preprocessing; second, explore hybrid architectures where fungal parts handle certain forms of memory or pattern recognition, while silicon handles high‑speed computation. This staged path reduces risk and accelerates the discovery of practical niches where biology makes sense.
Potential applications: where fungi could shine
Several use cases look particularly well suited to the strengths of fungal systems, especially when paired with traditional electronics:
Biologically integrated sensors that can live in the field for long durations without frequent maintenance. Mycelium‑based nodes could process data locally, reducing data transmission needs. Fungal bioelectronics could monitor soil moisture, nutrient content, and plant health, delivering real‑time feedback to optimize irrigation and fertilizer use with minimal energy input. In polluted or remote environments, biohybrid devices might be deployed to track contaminants, acoustic signals, and other metrics, operating on small energy budgets. The soft, flexible nature of mycelial systems could lead to gentler, implantable interfaces or wound‑care devices that interact with human tissue with reduced mechanical stress. Mushroom‑based demos could help demystify bioelectronics, offering tangible paths to teach complex topics like memory, signal processing, and energy efficiency.
How this fits into the broader tech ecology
Biomaterials and bioelectronics are increasingly interwoven with mainstream tech strategies. The push toward sustainable computing aligns with ongoing efforts to lower energy consumption in data centers, optimize supply chains for electronics, and create long‑lasting devices that resist planned obsolescence. Fungal computing sits at the intersection of several trends: materials science, environmental stewardship, and the democratization of technology that invites researchers from diverse disciplines to contribute.
Temporal context and current momentum
In 2025, the conversation about fungi in computing gained notable momentum thanks to high‑profile publications and pragmatic demonstrations. Researchers emphasize that the field is still in early stages, but the pace of progress suggests that meaningful, fieldable prototypes could emerge in the next five to ten years. Meanwhile, the broader push toward eco‑friendly electronics is accelerating investment in green materials, recyclable design, and life‑cycle thinking for consumer devices.
Pros and cons at a glance

Experts caution that mushroom computers will not replace today’s laptops or smartphones in the near term. Rather, the near‑term horizon likely includes niche deployments where the ecological benefits and soft, compliant hardware are advantageous. For example, low‑power edge devices deployed in sensitive environments—such as wildlife reserves, farms, or clinics—could leverage fungal components for data preprocessing, anomaly detection, or energy harvesting amplification. As fabrication processes advance and control strategies mature, we could see modular bioelectronic elements that can be swapped in and out of standard hardware rigs, enabling hybrid systems that blend biology with silicon, rather than replacing it.
From a journalism and science communication standpoint, the mushroom computing conversation also matters because it reframes questions about sustainability in technology. It invites designers and policymakers to consider not only performance metrics, but also material lifecycles, recyclability, and how to minimize the environmental footprint of a world that increasingly runs on digital infrastructure. In that sense, the research carries social relevance beyond the lab bench and into classrooms, boardrooms, and makerspaces.
For readers of Revuvio, the takeaway isn’t that your next computer will be a cluster of living mushrooms. Rather, it’s that biology can inform radical new ways to store information, sense the world, and power devices with less energy and fewer materials. The field embodies a broader shift toward biodesign, where the lines between biology, materials science, and computer engineering blur to create more resilient and sustainable technologies. As with many emerging frontiers, the practical payoff will emerge step by step, often through small, reliable breakthroughs that add up over time.
The idea that The Future Of Computing Could Be Fungal is not merely a sci‑fi trope; it is a legitimate question about how to align technological progress with planetary boundaries. Mushrooms and their mycelial networks offer a natural blueprint for low‑power memory, adaptable materials, and biodegradable components. While challenges remain—variability, scalability, and integration—the path ahead is clearly worth pursuing. The next decade could bring living, biohybrid devices that complement silicon, delivering specialized capabilities that make our digital world more sustainable without compromising performance in the tasks where speed and precision matter most. As research advances, Revuvio will continue to translate these developments into practical insights, highlighting what works, what doesn’t, and where the opportunity lies for researchers, engineers, and informed readers alike.
