Paper Abstract

The US Office of Naval Research is funding a multi- disciplinary team to consolidate progress made in earlier programs towards self-contained microsensors to be embedded in a composite structure and queried using methods that methods that do not require physical connections. The sensors are to be left in place for the lifetime of the structure, are powered by the querying apparatus, and require no penetrations through the surface of the structure. This paper describes the integrated approach taken to realize the goal of an interrogatable strain rosette that is embedded 0.25' below the surface of a graphite composite plate. It also describes the progress to date of the sensor system itself.
