During our research time weexperimented with a few different types of materials, textures and densities.After trial and error we created a unique silicone mix that resembles thehuman skin and its different layers. As researchers of course, we conducteddifferent types of studies on novices and expert surgeons, resulting in aproduct that has received recognition by the local surgical authorities. Ourmission is to provide the highest quality of materials for the accuratedevelopment of surgical skills and we hope to expand our production and builtaffordable low and high fidelity simulation materials for training intraditional surgery, as well as in minimal invasive surgery.
