- Abstract:
- Pressure mapping provides knowledge about interface pressure between a person and the surface person is laying or sitting on. In medical applications the surface is commonly a bed or a wheelchair. The distribution of pressure applied to the skin by a supporting surface can be measured with a pressure mapping system. Depending on the magnitude and duration of the pressure, it can cause pain and tissue injuries, such as pressure ulcers to the person. By means of pressure mapping technology, it is possible to detect the areas where the pressure is concentrated and thus prevent the development of pressure ulcer. However, the properties of the commercial pressure mapping systems are usually inadequate for physiological measurements. In this study, properties of a commercial Xsensor pressure mapping system were studied. Measurements with test persons as well as measurements with a constant measurement load were carried out. Repeatability, sensitivity, temperature sensitivity and hysteresis of the pressure sensor were determined. Only the hysteresis was noticed to be poor while the other properties were satisfactory.
