| Popis: | Barium titanate-based ceramics Ba(Zr, Ti)O3-x(Ba, Ca)TiO 3 (BZT-xBCT) are considered as promising candidate material for piezoelectric sensors due to its superior piezoelectricity and non-toxicity. However, the piezoelectric temperature stability of the BZT-xBCT is poor around phase transition point, which restricts its application in different thermal environments. Therefore, it is crucial to improve the temperature stability of BaTiO 3 -based piezoelectric sensor. In this work, a laminated structure is proposed to improve the temperature stability of the piezoelectric material, and the piezoelectric coefficient at different temperatures has been measured. The results show that the laminated material in parallel structure exhibits suppressed and expanded peak value in a wide temperature range, which indicates improved temperature stability of piezoelectric property. Our results provide a general approach for developing advanced piezoelectrics with high temperature reliability. |
