Deterioration of the piezoelectric properties of (Bi_0.5Na_0.5)TiO₃ when using Na₂CO₃ as a sintering aid: A crystallographic and microstructural study

In this work, we present the impact of using Na₂CO₃ as a sintering aid and grain growth agent on the crystal structure, microstructure, and piezoelectric properties of (Bi_0.5Na_0.5)TiO₃ ceramics. The addition of Na₂CO₃ leads to a substantial increase in the grain size...

Effect of single-side stroke limiter on cantilever-based piezoelectric energy harvesting from low frequency vibrations

Piezoelectric transducers which rely on oscillating cantilever-type beams to harvest mechanical energy locally available in environments have been of great interest as a substitute for batteries. Most of the research efforts focus mostly on designs which aim at resonance matching to achieve maximum energy output without taking the mechanical...
