Energy harvesting by utilizing the movements of lower extremity

Nowadays, interchangeable batteries can create heavy and large volumes of weight which users need to carry with themselves. In order to solve this issue, extra effort has been spent on this research to design a biomechanical energy system which produces electrical energy.A new mechanism has been designed to enable production of the electrical energy. To activate this mechanism, various types of parameters can be used. These can be listed such as; walking, running, climbing up and down stairs and etc. As a consequence of these parameters, electrical energy can be obtained with respect to the forces gained by body weight and applied movement.The algorithms have been programmed in MATLAB software environment by cofiguring the mechanism with index of angular movement and speed with respect to time.According to the design, it is aimed to obtain electrical energy by mounting a simple mechanism with a dynamic gearbox and a dc generator on a human body.Keywords: Alternative energy source, Litium-ion battery, biomechanics, DC generator.
