SEM Scanner Sensing Apparatus, System and Methodology for Early Detection of Ulcers

An apparatus for in situ Sub-Epidermal Moisture (SEM) sensing of tissue, comprising:

• a flexible substrate,
• a first electrode and a second electrode that are both disposed on a common side of the flexible substrate;
• an insulating cover layer coupled to the flexible substrate and configured to act as a barrier between the tissue being measured and the first and second electrodes;
• and
• an electronics package that is individually wired to each of the first and second electrodes and configured to:
• receive a pressure applied over the first and second electrodes, and
• measure a capacitance between the first and second electrodes when the pressure is within a defined pressure range,
• wherein the capacitance is an indicator of SEM.
