Research Institution
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 operational cost. However, the scalability and applicability of SHM systems for the monitoring of large structures is still a challenge. The goal of the proposed effort is to develop the capability for enhanced in-situ structural health monitoring of large structures through embedded control of a large number of sensors and actuators. The effort focuses on development of “Flexible Smart Strips” for structural health monitoring. The strips will have the following innovative characteristics: Versatility and flexibility for application to structures of any geometry and configuration, Flexibility for ease of installation even in inaccessible structural areas, Built-in capability for data acquisition and processing, Ability to monitor the integrity of large structural areas, Enhanced damage detection capability, Extreme Portability and Low-cost. The project will leverage the Thin Film Transistor technology to provide benefits of flexibility, cost and performance. Phase I focused on demonstrating the feasibility of the concept while phase II will focus on the flexible smart strip prototype development and implementation issues.
