Smart Splint Development

Abstract

After suffering a fracture in an upper or lower limb, a plaster cast is placed on the affected limb. It is a very old and efficient technique for recovery from an injury that has not had significant changes since its origin. This project aims to develop a new, low-cost smart 3D-printed splint concept by using new sensing techniques. Two rapidly evolving advanced manufacturing (AM) technologies will be used: 3D scanning and 3D printing. This is possible thanks to the application of engineering on additive manufacturing techniques and the use of biocompatible materials available in the market. This study proposes the use of these materials and techniques, including sensor integration inside the splints. The main parameters considered to be studied are pressure, humidity, skin colour, and temperature. These aspects are combined and analyzed to determine any kind of unexpected evolution of the treatment. The goal of this study is to generate a smart splint by using biomaterials and engineering techniques based on the advanced manufacturing and sensor system for clinical purposes.
