Abstract

Shape memory alloys (SMA), some feromagnetic (FM) materials, feroelectric (FE) and piezoelectric ceramics show anomalous dimensional changes known as shape memory effect, magneto-striction, electro-striction and piezoelectric effect. However, there are remarkable difference in respect to maximum strain: up to 10% for shape memory alloys and two orders of magnitude less for feromagnetic and feroelectric materials. The advantages are that their dimensions can be modified not only by stress and temperature (SMA), but also by magnetic (FM) and electric (FE, PE) field. This results in competition, but also in distinctly different fields of application. In the countries with high level of technological development (USA, Japan, Germany) these materials are commercially applied in many fields, particularly in medicine and technic where they are used as sensors and actuators.
