team of scientists ohio state university in america I managed to produce it memristor fungi. each memristor It’s a component electronic Preserves the memory of resistance. Researchers have now created them based on: Also called mushroom or Chinese mushroom Shiitake mushroom. It’s a potentially game-changing advance sustainable computing.
These devices can store information and simulate brain connections. They offer similar performance to silicon chips, but with the advantages of being biodegradable, low cost, and scalable.
For details, innovation Published in a magazine Pro Swan And it opens the door to a new generation of greener and more accessible computers.
It was developed by John LaRocco, Kudosia Tamina, Ruben Petreaca, John Simonis and Justin Hillwith support from the Institute sling.
Scientists took into account the central question. It is a traditional memristor, neuromorphic computing, This technology, which mimics brain function, requires rare minerals and expensive manufacturing processes.
Able to efficiently store and process information, these devices are essential for applications in the following areas: artificial intelligencerobotics and self-driving cars.
However, its production has a significant impact on the environment and limits its availability. Faced with this challenge, researchers looked for sustainable alternatives that could reduce the cost and environmental impact of these components.
he Shiitake mycelium It presents as a promising option due to its ability to adapt to different conditions, resistance to radiation, and structure similar to neural networks.
The researchers therefore sought to explore whether shiitake mushroom mycelium could serve as a basis for creating functional memristors that can mimic synapses and store information.
To conduct the experiment, the team took nine samples. Shiitake mushroom in a Petri dish using an organic substrate under temperature and humidity controlled conditions.
Once the mycelium covered the entire surface, the samples were dried in the sun for 1 week to ensure long-term viability.
Subsequent rehydration with aerosolized deionized water restored the conductivity without changing the structure.
Each sample was connected to a specially designed circuit to evaluate its electrical behavior.
The researchers applied different voltages and frequencies and measured the response using a digital oscilloscope.
“We connected cables and probes to different points on the mushroom because each part has different electrical properties,” he explained. John LaRocco. “Depending on voltage and connection, different performance was observed,” he added.
The results were remarkable. Mycelial memristors are 5,850Hzthe accuracy is 90%. This means it can change state approximately 5,850 times per second, which is close to the slowest commercial memristor.
Moreover, the performance remained stable after the dehydration and rehydration processes, suggesting that these devices can maintain their functionality for long periods of time.
The researchers also observed that the performance of the mushrooms decreased as the voltage increased, but this effect was offset by adding more sample to the circuit.
“What you need to start exploring fungal computing can be as small as a compost pile and some homemade electronics, or as large as a growing factory with ready-made templates,” says LaRocco.
“Our findings demonstrate that fungal computers provide a scalable and environmentally friendly platform for neuromorphic tasks and can bridge bioelectronics and unconventional computing,” the researchers said.
The researchers emphasize that although the switching speed is slower than state-of-the-art memristors, the ability to parallelize the operation of multiple devices compensates for this limitation.
Moreover, the radiation resistance and adaptability of mycelium opens new possibilities for the development of intelligent systems and sensors in harsh environments.
future of sustainable computing It could be like a mushroom with a device that is sustainable, low cost, adaptable and has the potential to transform current technology.
