Fiber-optic surveillance system for monitoring progressive infrastructural decline

This technology is an optical sensing system that detects minor physical changes in building materials that result in structural breaches and leaks.

Unmet Need: Continuous monitoring of structural parameters for infrastructure breakdown

Current methods to monitor property damage include alert systems to detect emergent breaches. However, seemingly minor and undetected structural deterioration of homes and businesses can lead to events such as leaks that may result in extensive property damage. Therefore, implementation of a system that allows for continuous monitoring would provide a tremendous benefit by enabling property owners to make proactive restorations before serious infrastructural failure could occur. There are currently no methods for continuous monitoring and surveillance of properties for minor structural changes.

The Technology: Optical system for sensing changes in physical properties of building materials

This integrated optical system uses fiber optic-based sensors to monitor minor and progressive changes in building materials. A highly efficient algorithm locates specific regions of structural decline and automatically alerts to changes in physical parameters, such as moisture content. This cost-effective platform can be integrated with standard building materials, and may be applied to survey other structural elements such as gas lines.

Applications:

  • Alert system for home roof leaks
  • Leak risk assessment in large facilities and factories
  • Detection of gas and chemicals
  • Leak detection in oil pipelines and industrial reaction vessels
  • Environmental monitoring
  • Infrastructure monitoring

Advantages:

  • Detects progressive infrastructure breakdown
  • Prevents large-scale property destruction
  • Enables homeowners to take preventative measures
  • Increases safety in homes, workplace, and transportation
  • Limits damage due to spills, leaks, or explosions
  • Compatible with standard building materials
  • Cost-effective
