摘要：

Finite element studies have been conducted on the (Ba0.85Ca0.15)(Ti0.9 Zr0.1)O3(BCTZ) material fabricated at different sintering temperatures. BCTZ materials calcined at 300 oC for two hours and sintered at four different temperatures viz. 520 oC, 530 oC, 540 oC and 550 oC 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 540oC 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 520oC for two hours, sensing voltage increased by about 81% in d31 mode and 30% in d33 mode. Similarly, harvested power increased by about 238% in d31 mode and 60% in d33 mode. Actuation displacement in d31 mode was found to be more than that in d33 mode. It was observed that fabrication method has a profound effect on the material which can enhance the energy harvesting and sensing capabilities. © 2021 IOP Publishing Ltd.
