A predeveloped sensor placement algorithm is experimentally evaluated. This algorithm determines the optimal number of sensors needed to identify and detect all possible motions. Furthermore for each number of sensors used, the algorithm also provides the best location for the sensor(s). The optimal sensor placement design is experimentally verified on a 63-degree-of-freedom planar truss. Results show how the top five optimal locations for just one sensor are able to identify all four of the significant natural frequencies of the planar truss. The information given by the study is useful for ground testing and design in deciding where the sensors should be located and where possible backups can be placed.
