Plants sense and respond to many changes in their environment, both above and below ground.
Vivent records electrical signals, which are one of several signalling mechanisms used by plants.
These signals were discovered over 120 years ago but they are complex and hard to record and understand.
Specialised electronics and powerful computing means that it is now possible to decode these signals.
Plant use electrical signals to control growth, development and reproduction and to mount defenses to pests or disease.
By isolating certain plant responses we can detect specific stimuli. Alternatively we can measure variations to the expected signals to detect plant stress.
Plant communication is an exciting and intersting field of study.
