Scientists from the Cornell University managed to create a tree that generates energy by making use of flittering synthetic leaves that are connected to the stem of the tree. They named their latest invention “Piezo-tree.”
The tree generates electricity when the wind blows and makes the leaves move; their motion is transformed into energy. It is worth mentioning that the key component of the Piezo-tree is flexible piezoelectric material known as Polyvinylidene Fluoride (PVDF).
Researchers decided to use the material for their latest invention due to the fact that PVDF is able to resist unpredictable wind strength. More information is available here.
