On April 19, 2011, a recently developed, energy-autonomous wireless sensor network was tested in a large-scale live test. The collapse of a factory building located in Bad Säckingen, a city in the southwestern part of Germany, was intentionally triggered by an explosion. The sensors have been designed to measure, in the event of a catastrophic bombing, the pressure loads in the building structure. These sensors form a wireless network in areas such as building complexes and train tunnels and allow the transmission of relevant data signals to a security management system. The system indicates clearly which zones are safe to enter and forwards this information to rescue forces. Thus, rescue forces can immediately review the accessibility of the disaster zone and plan their operation to minimize risks and improve overall security.
