MEMS for Civil Infrastructure: Smart Aggregate for Concrete
The past few years have seen advancements in electrical engineering fields, such as microelectromechanical systems (MEMS) and microsensors. Together with more mature technologies like wireless data communication, these advancements have begun to make embedded microdevices for use in civil infrastructure a serious and cost-effective reality. This paper begins with a brief discussion of deterioration, damage, and current detection methods for concrete infrastructure. Following this background discussion is a presentation of the microsensor and electronic system technologies available for addressing deterioration and detection with distributed, embedded microdevices. Where possible, existing microsensors are proposed to augment or replace current nondestructive evaluation techniques. System technologies for power and communication are similarly proposed. In the area of local strength testing, where neither current NDE methods nor existing microsensors have proven effective, novel MEMS testing devices are proposed. Based on these needs and available technologies, the discussion concludes with a description of a concept being developed for a "Smart Aggregate" microdevice for distributed, embedded concrete infrastructure monitoring.
