摘要：As the use of renewable energy is increasing exponentially all around the world, the micro energy sources are no different. One of renewable micro energy generator is transducer which can make electricity from the relative displacement present within the system or the mechanical strain. A technique was created to maximize the collection of the electricity generated from a piezoelectric fiber, based on modes of transversal vibration. Created the numerical and computational models of the dynamic element's shape advancement issue. Normal strain top generation was expanded by 49%. The energy rise was 16%. The exploratory stands and strategies were created for the test confirmation of the depicted numerical modeling results. Comes about gotten from the try utilizing the holography method were compared to hypothetically gotten eigen frequencies and mode shapes, and the mistake does not surpass 3%.
