SEM scanner sensing apparatus, system and methodology for early detection of ulcers

摘要

UC10-380-2FP (UC-2010-380-2_FP-LA) A handheld, conforming capacitive sensing apparatus configured to measure Sub-Epidermal Moisture (SEM) as a mean to detect and monitor the formation of pressure ulcers. The device incorporates an array of electrodes which are excited to 5 measure and scan SEM in a programmable and multiplexed manner by a battery less RF-powered chip. The scanning operation is initiated by an interrogator which excites a coil embedded in the apparatus and provides the needed energy burst to support the scanning/reading operation. Each electrode measures the equivalent sub-epidermal capacitance corresponding and representing the moisture content.
