Zusammenfassung:	Systems and methods for detecting degradation and failures, includ types of failures, in a hose assembly are disclosed. One system includes a hose degradation monitoring circuit having a hose assembly including a hose having first and second conductive layers, and a degradation monitoring circuit configured to detect a resistance of the hose across the conductive layers. The degradation monitoring circuit includes a voltage source electrically connected to the first conductive layer, and a resistor electrically connected between the second conductive layer and ground. The degradation monitoring circuit further includes a voltage monitoring circuit electrically connected between the resistor and the second conductive layer, to periodically monitor a voltage at the location and detect a possible failure of the hose assembly upon determining that, based at least in part on a change in the voltage at the location over time, a resistance of the hose assembly has passed a threshold level.
