Similar tendencies have also been reported in BNT‐based ceramics due to the formation of “ferroelectric‐antiferroelectric” and/or “polar‐nonpolar” phases …”

Through modification of the heat-treatment process using a higher heating rate and a lower binder burnout temperature, the piezoelectric performance of waterquenched 0.67Bi 1.05 FeO 3 -0.33BaTiO 3 (BF33BT) lead-free piezoelectric ceramics was improved. The observed physical properties of BF33BT ceramics were very sensitive to the process temperatures. The sintering temperature (T S ) was changed within a narrow temperature range, and its effects were investigated. The largest rhombohedral distortion (90°-α R = 0.14°) and tetragonality (c T /a T = 1.022) were observed for the ceramic sintered at 980°C, and its Curie temperature was 476°C.This ceramic showed good piezoelectric properties and large grains; the piezoelectric sensor charge coefficient (d 33 ) was 352 pC/N, and the piezoelectric actuator charge coefficient (d Ã 33 ) was 270 pm/V. The high piezoelectric performance and low T S of BF33BT ceramics indicate their potential as new low-cost eco-friendly lead-free piezoceramics.

“…Due to the inherent concern that lead-based piezoelectric materials may cause environmental and human health problems, the investigation on lead-free piezoelectric materials has seen rapid growth since the early 2000s. Four different types of lead-free piezoelectric materials have been widely applied for piezoelectric devices including (K, Na)NbO 3 (KNN)-based [68,69], BaTiO 3 (BT)-based [70,71], BiFeO 3 (BF)-based [72,73], and (Bi, Na)TiO 3 (BNT)-based [74,75] piezoelectric ceramics and thin films. Among them, BF-based ceramics demonstrate outstanding ferroelectric and piezoelectric properties, which is especially suitable for high temperature applications due to their relatively high Curie temperature [76][77][78].…”

The objective of this article is to review the recent advancement in piezoelectric micromachined ultrasound transducer (PMUT) technology and the associated piezoelectric materials, device fabrication and characterization, as well as applications. PMUT has been an active research topic since the late 1990s because of the ultrasound application needs of low cost large 2D arrays, and the promising progresses on piezoelectric thin films, semiconductors, and micro/nano-electromechanical system technology. However, the industrial and medical applications of PMUTs have not been very significant until the recent success of PMUT based fingerprint sensing, which inspired growing interests in PMUT research and development. In this paper, recent advances of piezoelectric materials for PMUTs are reviewed first by analyzing the material properties and their suitability for PMUTs. PMUT structures and the associated micromachining processes are next reviewed with a focus on the complementary metal oxide semiconductor compatibility. PMUT prototypes and their applications over the last decade are then summarized to show the development trend of PMUTs. Finally, the prospective future of PMUTs is discussed as well as the challenges on piezoelectric materials, micro/nanofabrication and device integration.

“…Various lead-free piezoelectric materials have been studied, and representative leadfree piezoelectric ceramics can be broadly divided into four types: (Bi,Na)TiO 3 (BNT)based [12][13][14], (K,Na)NbO 3 (KNN)-based [15][16][17], BaTiO 3 (BT)-based [18][19][20], and BiFeO 3 (BF)-based [21][22][23].The phase transition temperature and piezoelectric characteristics are the two most critical parameters for replacing lead-based piezoelectric materials. Therefore, numerous methods and mechanisms have been studied to improve the phase transition temperature or increase the piezoelectricity of lead-free piezoelectric materials to compete with the properties of lead-based piezoelectric materials.…”

Lead-Free BiFeO3-Based Piezoelectrics: A Review of Controversial Issues and Current Research State

2022

View full text Add to dashboard Cite

Lead-free electroceramics represent an emerging area of research that has the potential to enable new green advances in electronics. Research has mainly focused on the development of new piezoelectric materials for replacing lead containing oxides exhibiting superior electromechanical behavior. Lead-free BiFeO3-based materials are not only the promising candidates to replace lead-based materials but also show intriguing properties which may inspire innovative material design for the next generation of lead-free piezoceramics. This review aims to highlight the current state of research and overlooked aspects in lead-free BiFeO3-based ceramics, which could be insightful in elucidating certain controversial issues. Current strategies to reduce high conductivity, influence of chemical heterogeneity on both functional properties and crystal structure, effective heat treatment procedures, and the role of pseudo-cubic structures on the enhancement of piezoelectric properties are subjects of highlighted within this review as they have a significant impact on the quality of BiFeO3-based lead-free piezoelectrics (but are often disregarded).
