This paper presents optimal electrode shape design methods for the multi-mode sensors that could detect the structural multiple modes. The structure used for this study is an isotropic cantilever beam type with a PVDF (polyvinylidene fluoride) which is bonded onto the structure as a sensor. The shape optimization problem is solved by using Genetic Algorithm (GA) and Super-position method. The performance of analytical optimal shape sensor is validated by experiment. The results show that the obtained electrode shape sensors have good performance to detect the multiple vibration modes simultaneously.
