Paper Abstract

The SMART Layer (reg. TM) manufactured by Acellent is a thin flexible layer with a network of miniature piezoelectric actuators and sensors that can be embedded inside or mounted onto metal and composite structures to acquire information on structural integrity. Currently, SMART Layers (reg. TM) are used to assess the condition of structures and to monitor impact events. The layers can be used to perform built-in structural inspection by exciting the devices with a periodic or transient burst controlled input and analyzing the corresponding structural response. The technology can also be applied to areas concerned with Homeland Security. For example, the technology can be used for motion monitoring and monitoring of structures used in defense applications. By having a network of sensors that monitor loads on a structure, it is possible to monitor the movement of people by measuring the loads exerted by them. The SMART Layer (reg. TM) technology can be used to enhance the readiness of structures used for homeland defense such as manned and unmanned aircraft, missiles and radar systems. It can also be used to monitor a pipeline network for any terrorist related activity that can potentially damage the pipe system. A brief overview of such potential applications is presented here.
