Scientists of the University of Silesia in Katowice (UŚ) designed a new method of obtaining lead-free piezoelectric ceramic (BLTF) by modifying the structure of a unit cell in its crystal lattice. The invention has already obtained the patent. 

The material with a perovskite structure shows better piezoelectric properties, it is also safe for humans and the environment thanks to the elimination of harmful lead from its composition. The authors of solution are Dr Beata Wodecka-Duś, the University of Silesia, Dr Małgorzata Adamczyk-Habrajska, the University of Silesia, Dr Eng. Lucjan Kozielski and Dr Dariusz Bochenek, the University of Silesia.

Piezoelectric ceramics are interesting products for the electronics and electrotechnical industries. They can be elements of sensors for measuring mass, force or acceleration. They generate acoustic and ultrasonic waves and that’s why they can be used in ultrasound, in parking sensors and in audio devices such as speakers.
