Abstract
Disclosed herein are a circuit and a method for the electrical data read-out of a large-area sensor flexible circuit. This circuit incorporates sensing elements of two types, and is therefore used for the measurement of two physical metrics associated with the etiology of pressure ulcers, one of which might be pressure. The flexible circuit is large enough to cover the area(s) of the human body. The flexible circuit comprises electrically of the following components: (a) a passive or active matrix array, and (b) its scanning/read-out circuitry. The matrix array (a) comprises further of (i) two electrodes for the sensing of pressure in each sensing element (sensel) of the array, and (ii) two electrodes for the sensing of another metric (temperature, moisture, pH, etc.) in each sensel. One electrode is shared (common) between the first (i) and the second (ii) sensor in the sensel.
