Abstract
A system to prevent the creation of pressure-wounds in a subject is provided, comprising at least one pressure detection mat comprising at least one layer of an insulating material sandwiched between first and second layers of conducting and a second layer of conducting strips overlapping at a plurality of intersections forming sensors, a driving unit configured to supply electrical potential selectively to the first layer' conducting strips, a control unit wired to the second layer's conducting strips and configured to control the driving unit and to receive data from the sensors, a processor configured to monitor electrical potential on the second layer's conductive strips to calculate impedance values and determine accumulated pressure applied thereto by calculating a summation of pressure measured by the sensor at predetermined intervals, and at least one display configured to present indications of pressure distribution and accumulated pressure.
