【作品介紹 Description】

Continuous flows of energy are involved in Nature. Energy neither arises nor disappears, but only passes from one state to another. Emerging technologies and contemporary cultural context allow scientists and artists to invade this cycles of energy transformation. This project offers one of the new approaches to invading the aforementioned cycle. Namely, this study explores the potential of generating electricity using repetitive movements of tree branches. To achieve this goal, first an analysis of tree branch movements was carried out. This stage included tracking fluctuations of branches in order to identify the average deflection from the initial position of the branch. As a result, it was found that, depending on the type of branch, its height and the wind speed, fluctuations may vary from 1 to 25 cm. Further work was carried out to develop a mechanism capable of converting these waverings into electricity. For this purpose, it was decided to use the piezoelectric method of generating electricity. The developed mechanism consists of a piezo disc fixed between the movable part, which is the rod and the static element, which is a branch fastening. During the development of the project, the result was obtained that each cycle of the branch movement generates a charge equal to 3.6 volts with a current of 0.1 amperes and a duration of 200 milliseconds. The project proposal involves the use of generated electricity for the purpose of off-grid navigation in urbanized spaces, where nature in the form of a green infrastructure has partially gone out of control, creating shaded and wild areas. The application of this technology is not limited to navigation, the range of possible applications depends on the number of 'Anemokinetics' mechanisms.
