The firm raise in energy uses tied with pollution has encouraged the researchers to be focused on alternative ways to get pollution free non conventional energy sources. The world is slowly but surely moving towards a rigorous energy crisis, due to an increasing order of energy crossing its supply. Numerous researches are going on to develop different material, different ways and also different renewable fuels which can produce energy. In recent development, by collecting the energy from the environment with the help of wind, sun, water etc. are normally used to give power directly to electric devices or are stored in batteries. This is termed as energy harvestation. In recent studies a new way to harvest energy is seen by using piezoelectric material, generally deals with the energy produced due to mechanical vibration. When a piezoelectric element is strained, it charges up electrically. It is clearly observed that structural elements produce vibration when it comes under dynamic load. Usually different bridge structures come under dynamic load, as an example when a loaded vehicle passes through a bridge. A bridge structure can be compared with a beam under different boundary conditions. So if a precise study is done on energy harvestation by using piezoelectric patch from a beam under dynamic load then it can show a direction to utilize the vibration of different structures to generate electrical voltage. Some researchers have used the piezoelectric patch as long as the beam length to harvest energy. Since Piezoelectric material is very costly so it is not possible to use it to cover up the whole length of a bridge. In this study it is focused to find out a optimized way by which the vibration of different structures can be utilized to generate electricity. A mathematical as well as a finite element model is developed to obtain the voltage output from piezoelectric patch for different conditions. Keywords— ABAQUS, Piezoelectric, Dynamic, Mode shape
