Resumo(s)
Structural health monitoring has long been identified as a prominent application of Wireless
Sensor Networks (WSNs), as traditional wired-based solutions present some inherent limitations such as
installation/maintenance cost, scalability and visual impact. Nevertheless, there is a lack of ready-to-use
and off-the-shelf WSN technologies that are able to fulfill some most demanding requirements of these
applications, which can span from critical physical infrastructures (e.g. bridges, tunnels, mines, energy
grid) to historical buildings or even industrial machinery and vehicles. Low-power and low-cost yet
extremely sensitive and accurate accelerometer and signal acquisition hardware and stringent time
synchronization of all sensors data are just examples of the requirements imposed by most of these
applications. This paper presents a prototype system for health monitoring of civil engineering structures
that has been jointly conceived by a team of civil, and electrical and computer engineers. It merges the
benefits of standard and off-the-shelf (COTS) hardware and communication technologies with a minimum
set of custom-designed signal acquisition hardware that is mandatory to fulfill all application requirements.
