Smart knee cap started as a solution design project by four medical system engineering students from Otto Von Guericke University Magdeburg. Creating an appropriate project plan requires defining  objectives and division of tasks accordingly. Task division was done based on group member's interests as follows: programming, hardware implementation and 3d design of the circuit box for our final circuit. The main concentration of the project is on helping people to avoid  exercise related knee injuries. Smart Knee Cap can track and measure knee different angles with high accuracy. Our main goal was that not only healthy people can benefit from our product, but also people who suffer from knee diseases can use the product easily.
