Smart materials are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli (stress, temperature, ligot, moisture, pH, electric or magnetic fields, pressure, etc.). This change is reversible and can be repeated many times. In their various forms, these materials can perform as actuators, which can adapt to their environments by changing characteristics such as shape and stiffness, or as sensors, which provide the actuators with information about structural and environmental changes.There are a wide range of different smart materials. Each offer different properties that can be changed. The combination of physics, chemistry, and the focus on the relationship between the properties of a material and its microstructure is the domain of Smart materials. The development of this field allowed designing materials and provided a knowledge base for the different engineering applications.
This text is intended to present the basic fundamentals on a level appropriate for engineering students who have completed courses in physics and chemistry. The intent is to provide the students with a teaching text which presents the introductory knowledge of smart materials and its application. These texts are intended for students continuous the study of mechatronics and mechanical engineering because all engineering disciplines need to know about advanced materials. After the study of these materials students will be able: – to choose a new material that will have some desirable properties, – to understand the limits of materials and the change of their properties with use, – to select a material for a given use based on considerations of cost and performance.
