Scientists have invented tiny electronic tattoos for plants to help tell when they are thirsty.
The new tattoos can give people a better idea of when a plant needs water. This means plants may be looked after more carefully and at the right time. The invention was made by scientists who wanted to find a simple way to check on a plant’s needs.
The tattoos are electronic, but they are designed for plants rather than people. They act like small sensors that can notice changes in the plant. When a plant becomes thirsty, the tattoo can help show that something is changing. This could make it easier for people to understand what plants need.
The idea may be useful for gardens, farms and greenhouses. Instead of guessing when to water plants, people could use the tattoos to help them decide. That could save water and also help plants stay healthy.
This invention is unusual because it gives plants a kind of voice. Plants cannot speak, but these tattoos can share important information for them. Scientists hope inventions like this will help people care for plants better in the future.
