Identification of bedsore using electromagnetic waves for a non-contact detection system

Bedsores are injuries caused by pressure on the skin for a long time and stagnation of blood flow. The more such injuries progress, the longer the treatment period becomes. In some serious cases, surgery is required. Therefore, an early detection method is important. In this study, we develop a non-contact bedsore detection system by using electromagnetic waves. In this paper, we investigate a method using wavelet transforms to develop a more accurate bedsore detection method.
