Noncontact size detection method for bedsores

Abstract

Bedsores are injuries caused by prolonged pressure on the skin and stagnation of blood flow. The more the damage caused by bedsores progresses, the longer the treatment period becomes. Moreover, patients require surgery in some cases. Therefore, early detection is essential. In our research we are developing a noncontact bedsore detection system using electromagnetic waves at 10.5 GHz. In this paper, we extracted appropriate information from a scalogram and utilized it to detect the sizes of bedsores.
