The Promise of Nanoscale Sensors
Nanotechnology introduces the idea of nanosensors, miniature devices with the ability to monitor a number of factors at the microscopic level, including stress, pressure, temperature and corrosion. These sensors can be integrated directly into building materials such as concrete and steel or used as coatings on surfaces.
The advantages of nanosensors are multiple. They provide uninterrupted data on the structural condition of the infrastructure and allow engineers to identify problems at an early stage, anticipate maintenance requirements and avoid possible disasters. Such sensors have high sensitivity and make it possible to identify subtle structural changes that can go unnoticed when using conventional monitoring methods.
