structures, termed mesoscale structures (e.g. civil, aerospace, and energy
structures) is difficult due to their large size and complex geometries.
Additionally, there exists a lack of economic and scalable sensing technologies
that are capable of detecting, localizing, and quantifying local faults over a
structures global area. A solution to this local-global problem is the
deployment of an inexpensive dense sensor network that is capable of detecting
and localizing damage over a structure’s global area. </span></p>

The first consists of a sensing skin developed from a flexible capacitor that
is mounted externally onto the structure. When deployed in a dense sensor
network configuration, these large area sensors are capable of covering large
surfaces at low cost and can monitor both strain- and crack-induced damages.
The second sensing technology consists of smart-cementitious material doped
with multi-wall carbon nanotubes, which has been demonstrated to be suitable
for monitoring its own deformations (strain) and damage state (cracks).
Integrated into a structure, this smart cementitious material can be used for
detecting damage or strain through the monitoring of its electrical properties.</span></p>
