ABSTRACT:
Systems for monitoring structural health conditions of objects. Each system includes patch sensors attached to an object, wherein each patch sensor is capable of generating a wave upon receipt of an actuator signal and developing a sensor signal in response to the wave. The system includes a tree structured relay unit that has a root node and at least one lower level node that includes at least one leaf node connected to the patch sensors. The lower level node includes switches, wherein the switches are operated to establish a channel between the root node and a selected one of the patch sensors and wherein actuator signal or sensor signal is transmitted through the channel. The sensor signals are analyzed to monitor health conditions thereby prevent catastrophic failure.
