Remotely queried embedded sensors in composite structures

Embedded sensor technology in polymer-based structural composites has received much attention in recent years. Embedded sensors are critical to structural health monitoring in high performance applications, e.g. 'smart' skins and structures. To date, optical fiber sensors have been the principal sensing technique for these applications. However, some notable shortcomings of these sensors include difficulties with ingress and egress from part, and interdependence of strain and temperature measurements. This paper discusses an alternate approach for structural health monitoring: remote query of silicon microsensors embedded in composite structures. The technologies involved will first be reviewed, followed by a listing of the potential benefits of applying this technology. Next, a newly initiated program to demonstrate the feasibility of remote query techniques for structural monitoring of composites will be described.
