Embedded PZT Sensors Enhance Concrete Structure Monitoring
Embedded PZT Sensor Arrays for Comprehensive Local & Distributed Sensing of Concrete Structures
Tags: IIT Hyderabad, India, Construction & Smart Cities
Researchers have developed embedded PZT sensor arrays for continuous monitoring of concrete structures, from casting to their service life. These sensors use Lead Zirconate Titanate (PZT) patches to measure changes in material stiffness through electrical impedance, detect structural vibrations, and monitor stress wave propagation, enabling real-time structural health assessments. Applications include optimizing construction practices, such as determining formwork stripping times, and providing long-term monitoring for asset management in concrete structures. The sensors are robust, cost-effective, and designed for durability, offering a comprehensive solution for structural health monitoring. This innovation addresses a significant gap in the construction industry by integrating local and distributed sensing capabilities for enhanced structural maintenance.
