Researchers have developed fungal electronics, a new class of living electronic devices built from mycelium-based materials. These biological circuits can dynamically change their electrical impedance and generate voltage spikes when exposed to external stimuli. The technology represents a breakthrough in biocompatible computing, using living fungal networks as both sensors and processors.

Mycelium composites serve as the foundation for these devices, either in pure form or bound with other materials. The fungal networks respond to environmental changes by altering their electrical properties, making them ideal for sensing applications. Researchers have demonstrated that these living circuits can be integrated into wearable technology or function as standalone computing devices.

The field of fungal electronics opens new possibilities for sustainable, biodegradable electronics that can interface directly with biological systems. Unlike traditional silicon-based circuits, these living devices can self-repair and adapt to changing conditions. The technology could lead to applications in environmental monitoring, biomedical devices, and adaptive computing systems that blur the line between biological and electronic systems.
