Over the millions of years that plants have evolved, they’ve reacted to multitudes of stimuli for the sheer fact that they can’t get up and walk away. In doing so, vegetation releases tell-tale electrical signals that researchers believed can be harnessed to effectively turn plants into biosensors. Read more
