Simultaneous edge debonding monitoring and repair of dynamically loaded concrete structures strengthened with smart composite materials C P Providakis Department of Applied Science, Technical University of Crete GR-73100 Chania, Greece email: cpprov@mred.tuc.gr Keywords: PZT, Repair, Concrete, Health Monitoring, Electromechanical admittance Abstract.
The present work considers the possibility of simultaneous health monitoring and active repair of the edge debonding in dynamically loaded smart concrete structures strengthened with fiber reinforced plastic (FRP) composite materials.
In the present study, lead zirconate titanates (PZT), classified as piezoelectric materials are used as surfacemounted PZT admittance calculating sensor (labeled in Figure 1 as ACS) for the measure of the E/M admittance and PZT actuator (labeled in Figure 1 as PZTA) for the activation and the subsequent creation of appropriate forces to restore any observed debonding.

Tungsten oxide (WO3) film material is applied extensively because of its electrochromic property, gasochromic property, photochromic property, electrochemistry, etc.
In this work, the platinum-doped WO3 films [8, 9] were adopted for the sensor and the optical properties were discussed Experiment In the experiments of fabricating hydrogen sensitive films for SPR optic-fiber micro-sensor, tungsten trioxide was used as the basic materials, and the platinum-doped WO3 films were prepared with sol-gel method, magnetron sputtering method, and microemulsion method respectively, then the hydrogen sensitive properties of the films were tested.
