Embedded control of an Active Structural Integrity Monitoring System using interlaced PZT and Thin-Film Transistors

In recent years, Structural Health Monitoring (SHM) is increasingly being evaluated by the industry as a possible method to improve the safety and reliability of structures and thereby reduce their operational cost. However, the scalability and applicability of SHM systems for the monitoring of large structures is still a challenge. Sensors and actuators of a structural health monitoring system can be integrated with a large structure but may be difficult to control using externally located electronics. Acellent Technologies, proposes to develop innovative technologies for embedded control of a network of actuators and sensors using thin-film transistors. The resulting system will have the advantages of (1) versatility and flexibility for application to structures of any geometry and configuration, (2) enhanced resolution for structural integrity monitoring, (3) low-cost and (4) extreme portability. The development will utilize Acellent's current SMART layer technology that uses a network of sensor and actuators embedded on a thin dielectric film to monitor the health of a structure. Phase I will be aimed at development of a concept design using macroelectronics and demonstrating the working of a prototype system.
