Design of an orthopedic smart splint using nickel-titanium shape memory alloy

<span lang="EN-US">People with broken bones suffer from symptoms of muscular atrophy as a result lack movement, so it was necessary to find effective solutions due the relative pain they cause and difficulty movement after healing. In this paper, we proposed smart splint made nickel-titanium shape memory alloys (SMA) wires. These have unique properties compared other materials, most important which is maintaining original during manufacturing at certain temperature. Temperature, pressure, well humidity, were analyzed monitored while patient wore reach best possible results by using microcontroller. The showed that there significant improvement for muscles in short time when splint, percentage qualified muscle recovery increased more than 70% usual splint. wires used had an role rehabilitating these performing permanent local massage. different diameters wires, response temperature change recorded.</span>
