Systems for diagnosing/monitoring structural health conditions of objects. The system, which monitors structural health conditions by use of a plurality of patch sensors attached to an object, includes at least one bridge box and at least one relay switch array module having a plurality of switches. Each of the patch sensors is adapted to perform at least one of generating a wave upon receipt of an actuator signal and developing a sensor signal. The bridge box includes an analogue-to-digital converter (ADC) for converting the sensor signal to a digital signal. The switches are adapted to establish a channel between a selected one of the patch sensors and the ADC.
