Graphene “Tattoos” for Plants Could Form Neural Networks

Researchers at the University of Texas at Austin have developed a graphene tattoo that sticks directly onto leaves to monitor hydration in real time. The sensor acts as an artificial synapse, potentially enabling plant-based neural networks for forest fire and drought monitoring.

Key points

  • Graphene patch acts as a stick-on tattoo for leaves, measuring moisture via electric pulses without damaging the plant.
  • Sensor exhibits synaptic properties: adjustable conductance and short-term memory, suitable for neural network applications.
  • Researchers trained a single-layer perceptron to classify leaves as hydrated, normal, or drought-stressed using sensor readings.
  • Vision includes networked sensors on leaves, soil, and sap to aid farmers and forest rangers in real-time drought and fire risk assessment.
