A wireless biomedical instrument for evidence-based tissue wound characterization
Patients' skin integrity has long been an issue of concern in nursing homes and hospitals. Overall incidence of pressure ulcers for hospitalized patients is as high as 50%. The estimated cost of treating pressure ulcers ranges from $5,000 to $40,000 for each ulcer, depending on severity. A smart compact capacitive sensing wireless handheld system is presented which measures Sub-Epidermal Moisture (SEM) as a mean to detect and monitor early symptoms of ulcer development. The system was successfully verified in trials with 30 volunteers and is currently deployed for clinical trials in four nursing homes.
