In this paper, we proposed a smart splint made of nickel-titanium shape memory alloys (SMA) wires. These alloys have unique properties compared to other materials, the most important of which is maintaining the original shape during manufacturing at a certain temperature. Temperature, pressure, as well as humidity, were analyzed and monitored while the patient wore the splint to reach the best possible results by using a microcontroller. The results showed that there was a significant improvement for the muscles in a short time when using the proposed splint, as the percentage of qualified muscle recovery increased by more than 70% when using the usual splint. The wires used had an effective role in rehabilitating these muscles by performing a permanent local massage. due to the different diameters of these wires, a different response to temperature change was recorded.trueMedical devices | Microcontroller | Nickel-titanium | Shape memory alloy | Smart splintDesign of an orthopedic smart splint using nickel-titanium shape memory alloyArticle10.11591/ijeecs.v29.i3.pp1300-130910.11591/ijeecs.v29.i3.pp1300-13092-s2.0-85144682865
