Graphene “Tattoos” for Plants Could Form Neural Networks

# Graphene "Tattoos" Could Monitor Plant Health in Real Time Researchers have created tiny graphene patches that stick to plant leaves like temporary tattoos and measure moisture levels without damaging the plant, solving a major problem for farmers and forest managers who currently have to cut samples to check if crops or trees are healthy. These sensors could eventually work together as a network across entire fields or forests to warn farmers and fire departments about drought or fire risks before they become serious problems. The breakthrough matters because real-time plant monitoring could help prevent crop failures and forest fires by catching problems early.
