A sensor () for monitoring health of an associated article (A) (e.g., a fluid connector) including a sensing element () disposed along a length of an outer surface of the associated article, wherein the sensing element is configured to detect at least one physical property of the associated article and output an electrical signal in proportion to an amount of the physical property applied to the sensing element; and a mounting mechanism () configured to secure the force sensing element to at least a portion of the outer surface of associated article.

Embedded or clip-on device for health monitoring of an article

A sensor sleeve for use in detecting a failure in an article (e.g., a hydraulic hose), the sensor sleeve includes an insulator layer that separates two electrode layers. As such, the electrode layers deform to contact each other, which changes the impedance as measured across the electrode layers. The sensor sleeve is designed to change electrical impedance (resistance) due to fluid pressure initiating a hole through the sensor itself. The sensor sleeve will detect the fluid leak when the hole penetrates the sensor and brings the two elastic electrodes in contact with each other and/or the fluid, which when the fluid is conductive fluid, creates a signal path between the first electrode layer and the second electrode layer, which also changes the impedance as measured across the electrode layers.
