The field of practice explored is to provide a substitution for amputated limbs in the upper body. An amputation creates a dramatic change in the life of a patient. It directly influences the wellbeing, quality of life and their autonomy. Additionally, patients must cope with challenges in their family and social environment. Any research that can push the frontier of this field is a necessity considering the effect of positive.
Auxetic prosthetic focuses on using auxetic structure to create prosthetic muscle that can be used in upper body prosthesis A major constraint in the current prosthesis system is the weight of the arm. The use of additive manufacturing to print auxetic structure eliminates the use of actuators and minimises the number of motors used overall. The two components, the motor, and the actuators are designed to bring the most weight to the upper limb prosthetic system. By using auxetic materials dynamic properties we substitute actuators. The only objective of the motor is to induce the force small enough to create a chain reaction. Furthermore, the project highlights the sustainability of prosthesis by using PV cells to power prosthesis.
3D printing material specifically used for this application is Thermoplastic Polyurethane (TPU) because of its appropriateness for the application due it’s high flexibility and material properties. 3D models and simulation will be run to develop the best structure design.
