Finite element studies have been conducted on the (BCTZ) material fabricated at different sintering temperatures. BCTZ materials calcined at for two hours and sintered at four different temperatures viz. and for two hours were considered. The structure was subjected to base vibration and its dynamic effect was studied. Sensing, energy harvesting and actuation capabilities of the system was studied. It was observed that BCTZ material sintered at demonstrated maximum values for sensing voltage, actuation displacement and harvested energy. Actuator displacement was measured in terms of tip displacement of the cantilever beam. Compared to BCTZ material sintered at for two hours, sensing voltage increased by about in mode and in mode. Similarly, harvested power increased by about in mode and in mode. Actuation displacement in mode was found to be more than that in mode. It was observed that fabrication method has a profound effect on the material which can enhance the energy harvesting and sensing capabilities.
