SEM SEM SCANNER SENSING APPARATUS SYSTEM AND METHODOLOGY FOR EARLY DETECTION OF ULCERS

摘要

Is a hand held capacitance sensing device configured to measure subcutaneous water (SEM) in a sense of sensing and monitoring the development of a pressure ulcer. The device includes an array of electrodes excited in SEM scan and measurement in multiplexing mode and programming by a battery-free RF-driven chip. The scanning operation provides the necessary energy burst to support the scanning / reading operation; And an interrogator in which the coil embedded in the device is excited. Each built-in electrode represents the moisture content of the target surface and the equivalent equivalent capacitance of the skin is measured.
