A risk monitoring of buildings for natural and man-made hazards mitigation is discussed in this paper. Ubiquitous monitoring using a network of wireless sensors is one of the most promising emerging technologies for this purpose. A smart sensor based on the “Berkeley Mote” platform was introduced, and application to the next generation of structural health monitoring and control was recently proposed (Spencer et al., 2002, Spencer 2003). Herein, the performance of the “MICA Mote” is investigated through free vibration and shaking table tests of a two story steel structure. The MICA Mote as a wireless acceleration sensor is shown to have sufficient performance for the intended purpose.
