The few applications that exist to get an effective medical treatment of diseases like pressure ulcers, the high cost of studies that permit to establish an appropriate treatment for these diseases, some little research developed for these existing systems and the low regional implementation of the same systems in order to set the center of mass on bedsores' treatment systems and assess the effect of pressure caused in patients confined to a wheelchair for a long time, are many of the reasons that justify the development of a specific and efficient system which is able to detect the distribution of forces and analyze the pressure and the mass center in mattresses for hospital use.
