👩💻 Continuously input data from a sensor mounted on the femoral head of the implant to capture real-time loading conditions.
➗ Calculate resultant stresses acting on the femoral head by considering forces such as compressive and tensile stress based on the input data.
💻Communicate output to an end-user by displaying real-time stress data in a user-friendly format, allowing for quick assessments.
📊 Visualize the processed data graphically, plotting the resultant tensile stress with the ultimate tensile strength of bone.

As a group, we decided on a 3-part model, consisting of the stem, ball head, and liner. While another subteam was responsible for designing and modeling it, I contributed by 3D printing the prototype. This allowed me to directly see our design come to life and see its assembly align with our objectives.

My favorite part of this project was working on the computer program. My partner and I had the creative freedom to approach the program however we wanted, as long as we met the core objectives. This gave us the chance to learn as we went, experimenting with different methods such as using Python's GPIO library to interface with the Raspberry Pi and using Matplotlib for graphs.
