Vibrational energy harvesting is a growing field in research area to fulfil need of power requirement in wireless sensor network and small electronics devices. Vibration occurs in environment which can be utilised to produce maximum power at resonant frequency by converting vibrational energy to electrical energy by use of piezoelectric laminated cantilever beam so namely as piezoelectric energy harvesting. Present work is done on modelling and analysis of piezoelectric cantilever beam by varying length of piezoelectric patch here PZT- 5A is used for present study. Also different materials of cantilever beam have been considered to compute best material which should be used according to applications. This present research has been carried out by keeping in mind as system should have low weight, high voltage output and also last longer power supply. Static and Harmonic analysis of piezolaminated cantilever beam are performed in ANSYS R15 software. Solid model is developed and analysed by use of ANSYS finite element software. By doing these analysis power and voltage output comparison have been done lengthwise and materialwise. According to need of output power in the application, can be obtained by varying the dimension of piezoelectric patch and different materials of cantilever beam.
