Lead-Free Piezoelectric Transducers

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control
Research activities on lead-free piezoelectric materials have been ongoing for over 20 years. Generally, the applicability of the main material families is less universal than that of lead-based compositions such as lead zirconate titanate, but in some cases, the corresponding applications have already been identified. Due to the extensive research, it

Lead-free piezoelectric ceramics and thin films

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2010
Recent progress in lead-free piezoelectric ceramics and thin films with special emphasis on alkaline niobatebased and bismuth sodium titanate-based systems is reviewed concisely. Modifications of potassium sodium niobate (KNN) ceramics are presented and subsequent improvements in the electrical properties are summarized. Special attention is devoted to

Lead-free piezoelectric flexible films [PDF]

, 2020
The growing interest in science community today is finding the ways to safely use mechanical energy which is being released in small portions around us. The idea of this work is to use vibrational energy present everywhere in small quantities to power the small-scale electronic devices used in everyday life.

Lead-Free Piezoelectric Ceramics

2010
A number of new lead-free electroceramics have been developed based on the known lead-free ferroelectric system Bi0.5Na0.5TiO3-Bi0.5K0.5TiO3 (BNT-20BKT) at the morphotropic phase boundary by introducing small amounts of K0.5Na0.5NbO3-Bi0.5K0.5TiO3 (KNN-03BKT).

Applications of Lead-Free Piezoelectrics

2011
Our twenty first century will face a sustainable society, which requires (a) usage of nontoxic materials, (b) disposal technology for existing hazardous materials, (c) new energy source creation, and (d) energy-efficient device development. Piezoelectric devices seem to be all-around contributors and a key component to the above-mentioned four R&D ...

Perovskite Lead-Free Piezoelectric Ceramics

2011
Lead zirconate titanate (PZT)-based piezoelectric materials are the most widely used piezoelectric materials for electromechanical devices. However, due to the toxicity of lead, there is a strong interest in the development of environmental friendly lead-free piezoelectrics.
