De la mémoire informatique « champipi ». Original. Extraits:
LaRocco and co-authors grew shiitake mushrooms (Lentinula edodes), dehydrated the mycelium, and connected samples to electric circuits, which were used to apply a range of voltages and frequencies, using both square and sinusoidal waves.
The samples’ resistances changed, depending on the inputs, providing a memory. "We would connect electrical wires and probes at different points on the mushrooms because distinct parts of it have different electrical properties," LaRocco said. "Depending on the voltage and connectivity, we were seeing different performances."
