CANADA: Using semi-conductive polymers, both analog and digital electronic circuits can be created inside living flowers, bushes and trees, as researchers at Linköping University Laboratory for Organic Electronics have shown. The results are being published in Science Advances. With the help of the channels that distribute water and nutrients in plants, the research group at the Laboratory for Organic Electronics, under the leadership of Professor Magnus Berggren, have built the key components of electronic circuits. In an article in Science Advances, they show how roses can produce both analog and digital electronic circuits, which over the long term could be used, for example, to regulate the plant’s physiology. Traditional electronics send and process electronic signals, while plants transport and handle ions and growth hormones. In organic electronics, based on semi-conductive polymers, both ions and electrons can serve as signal carriers. With the help of organic electronics it therefore becomes possible to combine electric signals with the plant’s own, as if translating the plant’s signals into traditional electronics. With inexpensive organic electronics integrated into plants, a long range of possibilities opens up – such as utilizing energy from photosynthesis in a fuel cell, or reading and regulating the growth and other inner functions of plants.
