The Takeaway

Fungi use tiny electrical pulses to communicate across vast underground networks of mycelium. This new device taps into those pulses, allowing the fungus to act as a self-healing, biological computer interface. It can detect everything from subtle temperature changes to the presence of specific toxins without needing 14 different electronic parts. Because the sensor is alive, it can repair itself if damaged and consumes very little power. This opens the door to living buildings and environmental monitors that are part of the ecosystem they are watching. It is a major step toward merging biology with digital technology.

From the abstract

Multimodal environmental monitoring conventionally requires a suite of purpose-built transducers, each constrained to a predefined target. Here, we present MIND (Mycoponically Integrated Network Device), a platform that sustains living fungal mycelial networks on porous bioceramic substrates and reads their passive extracellular voltages. Without hardware modification, a single device produces distinguishable bioelectrical responses to 14 stimuli spanning chemical, optical, mechanical, thermal,
