Abstract
This paper investigates the use of the SansEC smart sensing technology towards mea-surement of bending and torsional deflections on a flexible plate. It is demonstrated that bending and torsional deflections result in changes in the frequency response of the SansECsensor. An experimental setup comprising of SansEC sensors mounted on a flexible plateis constructed, and this model is subjected to dynamic bending deflections and static tor-sional deflections, in separate tests. Frequency measurements of the SansEC sensor arerecorded, and a post-experimental data analysis is conducted. These results demonstrate astrong correlation between the plate deflections and the frequency response of the sensor,and demonstrate significant promise for use of the SansEC sensor towards measurement ofwing deflections in morphing aircraft applications.
