Scientists in Singapore have determined that by monitoring the electrical signals emitted by plants, a communication channel can be established between people and plants.

According to The Straits Times, a group of researchers from Nanyang University of Technology (NTU) in Singapore determined that communication with plants can be established with the help of a conductive material that detects the electrical signals emitted by plants and provides instructions to the plant through signals.

Stating that each plant reacts to the conditions around it by emitting an electrical signal just like a brain, the researchers communicated with the plants via a smartphone with a conductive material placed between the leaves.

As part of the research, an experiment was conducted on Venus flytrap. A 3-millimeter-thick electrode (material that transmits electrical signals) was placed in the plant’s traps with the aid of an adhesive known as “thermogel”.

It was observed that the plant, which received the electrical signal sent by the scientists via the smart phone, closed its traps within 1.3 seconds. In the next step, the flycatcher grabbed a half-millimeter-thick wire with the help of a robotic arm to which stronger signals were sent.

Experts conducting the study stated that the plant behaved like “a robot that could be controlled electrically by humans”.

On the other hand, it was emphasized that the electrodes can be used as a “plant whisper” that detects the unusual signals emitted by the plant, and thus more careful care can be given to the plant.

The research has been published in the journal “Nature Electronics”.
