Abstract
A multi-functional sensor system for simultaneously monitoring various parameters such as the structural, chemical and environmental conditions associated with a medium to be monitored, e.g., bridges, high-rise buildings, pollution zones, is provided wherein the system includes at least a plurality of wireless multi-functional sensor platforms embedded in the medium in which an interrogation unit transmits power and receives responses. Each wireless multi-functional sensor platform includes multiple channels for accommodating a plurality of sensor types to simultaneously monitor the parameters associated with the medium. Thus, the wireless sensor platforms are formed to include those sensor types which are considered germane to the intended medium to be monitored.
