 Plants are normally thought of as passive creatures in the environment. Contrary to this, they can not only sense what's happening around them, but also respond and display naturally. In our digital and physical interfaces, these are the two essential elements to complete an interaction loop. Through cyborg botany, we power some of our digital functions with the natural abilities of plants themselves. We envision such a bridge between the plants and the digital world to be bidirectional and deeply integrated. To explore this, we adopt an approach to move the electronics from outside to inside the plants. We keep a plant in a water-soluble polymer product that grows a single conductive channel inside a plant. We connected this internal wire to sampling instrumentation, turning a plant into an antenna or an inconspicuous sensor to detect motion and more. In a second case study, we show examples to not only listen to signals inside the plant, but also circuits that could send signals to them. We designed a live-view software in which clicking on a leaf sends it a corresponding signal. When a user clicks in the software, the corresponding leaf is closed, essentially turning the plant into a display. Integration of sensing and display together in this way, the bidirectionality, is an important factor for design. The pervasiveness of plants then allows us to think of new applications. Plants are self-repairing, self-regenerating organisms available at scale. Through cyber botany, we envision a convergent design world in which we re-appropriate our natural capabilities for a new bio-interaction design.
