Scientists in Singapore created a way to communicate between humans and plants via a smartphone. A team from Nanyang Technological University developed a technology that allows electrical signals to be sent that would facilitate dealing with plants, according to the "straits times" website.
The technology is very similar to brains, in that plants send electrical signals to respond to their environment, showing signs of distress or poor health. For example, it is now possible to notify you that there are insects on a plant leaf so that you can catch it immediately.
The advanced method relies on a smartphone and a 3 mm wide electrode, which is placed on the plant, through which it can send alert signals. So the electrode can be considered a "plant whisper".
