Researchers at The Ohio State University have created living computers powered by mushrooms, specifically shiitake fungi. These organic systems, called fungal memristors, replicate the memory functions of traditional computer chips while providing a sustainable and biodegradable alternative.
Understanding Fungal Memristors
Fungal memristors retain information about past electrical states, similar to how human brains store memories. In this study, the team cultivated shiitake mushrooms and trained them to act as these organic memory devices. When researchers connected the mushrooms to electronic circuits, they switched between electrical states thousands of times per second, demonstrating their potential as eco-friendly alternatives to conventional semiconductor components.
Advantages Over Traditional Electronics
One major advantage of using mushrooms in computing is their low power consumption. John LaRocco, the lead author of the study, explained, “We can develop microchips that mimic actual neural activity, so the devices don’t need much power for standby or when idle.” This characteristic makes fungal memristors ideal for edge computing, wearable devices, and autonomous systems, where energy efficiency matters most.
Implications for Sustainable Technology
Mushroom-powered computers mark a significant step toward sustainable technology. Unlike traditional silicon-based electronics, fungal circuits biodegrade naturally and require minimal environmental resources to produce. This innovation allows engineers to create computing systems that remain effective while reducing ecological impact.
Future Prospects
Although still in early stages, Ohio State researchers plan to optimize cultivation methods and miniaturize fungal devices to boost performance and scalability. With further development, mushroom-powered computers could transform computing, offering a sustainable and efficient alternative to traditional electronics.
