(IT-NEWSWIRE.COM, March 12, 2019 ) The piezoelectric ceramic is a kind of functional ceramic materials which can create electricity when subjected to a mechanical stress. They will also work in reverse, generating a strain by the application of an electric field. In sensors they make it possible to convert forces, pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers and actuators they convert electric voltages into vibrations or deformations.
The Science
Piezoelectric ceramic materials are ionically bonded and consist of atoms with positive and negative charges, called ions. These ions occupy positions in specific repeating units (called unit cells). If a unit cell is non-centro symmetric, i.e. lacking a centre of symmetry, then the application of a stress produces a net movement of the positive and negative ions with respect to each other and results in an electric dipole or polarisation.
The degree of polarisation is dependent upon the stress and whether tensile or compressive stresses are applied affects the charge produced. The dipoles, which are present due to the non-centro symmetric structure, form domains that are regions where neighbouring dipoles have the same alignment.
Initially the domains are randomly oriented (see figure on the left) and there is no overall polarisation of the ceramic and therefore it exhibits I no piezoelectric effect. By applying heat and a strong DC field the domains are subjected to 'poling', causing the domains that are nearly aligned to the field to grow at the expense of those at differing alignments. After cooling to room temperature and removing the DC field, the domains are 'locked' resulting in an overall alignment and the material is now piezoelectric.
The market for Lead Magnesium Niobate (PMN) held the largest share of the piezoelectric materials market owing to their high piezoelectric sensitivity and ability to acquire desired shapes and sizes. Currently, the most widely used piezoelectric ceramic material is PMN. It is used in a variety of applications, including medical, industrial, and automotive.

In the global piezoelectric devices market, APAC held the highest share in 2015. Globally, the largest amount of research on piezoelectric materials and devices is undertaken in Japan. Several experiments on microscale applications of piezoelectric technology have been carried out in Japan, including the usage of this technology in floors of train stations to generate electricity. Owing to this, the market in APAC is expected to grow at the highest rate in the coming years.
Global giant manufactures mainly distributed in Europe. The manufacturers in Japan have a long history and unshakable status in this field. Manufacturers such as MURATA and TDK have relative higher level of product’s quality. As to British, MORGAN has become as a global leader. In Germany, CeramTec leads the technology development. Most of Chinese manufactures locate in Jiangsu, Guangdong and Zhejiang province.
According to this study, over the next five years the Piezoelectric Ceramics market will register a 4.0% CAGR in terms of revenue, the global market size will reach US$ 9850 million by 2024, from US$ 7780 million in 2019. In particular, this report presents the global market share (sales and revenue) of key companies in Piezoelectric Ceramics business, shared in Chapter 3.
