Analysis of designing and application of Surface Acoustic Wave stress sensors (SAW-SSs) to operational safety of buildings and other engineering constructions was the main topic of our previous paper [1]. SAW stress sensors (SAW-SSs) measure the stress existing on the surface of piezoelectric base, measuring the delay of the SAW signal. The stress in SAW-SS is caused by the measured stress in elements of constructions. In this paper the modified SAW-SS is considered. The modified SAW-SSs are bound to the linear or surface elements of constructions indirectly, on supports. This new system diminishes influence of the casings and temperature at the results of measurements. The modified and previously proposed SAW-SSs may be used to measure the stress in bent elements of the construction and may also be applied to the measurement of bending instability of rods in truss or lattice constructions. The monitoring and warning systems signalling overstress or bending instability may be built using SAW-SSs.
