This monograph provides researchers, engineers, postgraduates and lecturers working in the field of ferroelectric or piezoelectric and related materials with features of the structure-property relationships in modern piezo-active composites. These are piezoelectric composites which are active dielectric materials, which can be poled ferroelectric ceramics or domain-engineered single crystals poled along specific crystallographic directions. Current knowledge of the effective physical properties of these materials is lacking especially due to gaps of information in physical, chemical, microgeometric and technological factors. For composite and transducer design purposes, the expected properties of these piezo-active materials have been theorized through models by the authors and proven in experiments. Various well-known journals have published this research, among many others: Smart Materials and Structures; Journal of Physics D: Applied Physics; IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control; Acta Materialia.The book summarises and generalises a series of authors' works on the problem of the effective properties and related parameters of modern two- and three-component piezo-active composites wherein the microgeometric factor plays the dominating role. Specific examples of the performance of composites based on domain-engineered single crystals are also discussed. New trends are described in the research of modern piezo-active composites with the aim of filling the gaps in piezoelectric materials science. The primary goal of the book is to show advantages of different methods being applied to manufacture and study the functional composites that are suitable for piezoelectric energy harvesting, hydroacoustic, sensor, actuator, and other transducer applications.

This book is devoted to the systematic description of the role of microgeometry of modern piezo-active composites in the formation of their piezoelectric sensitivity. In five chapters, the authors analyse kinds of piezoelectric sensitivity for piezo-active composites with specific connectivity patterns and links between the microgeometric feature and piezoelectric response. The role of components and microgeometric factors is discussed in the context of the piezoelectric properties and their anisotropy in the composites. Interrelations between different types of the piezoelectric coefficients are highlighted. This book fills a gap in piezoelectric materials science and provides readers with data on the piezoelectric performance of novel composite materials that are suitable for sensor, transducer, hydroacoustic, energy-harvesting, and other applications.

The book is devoted to the problem of microgeometry properties and anisotropy relations in modern piezo-active composites. These materials are characterized by various electromechanical properties and remarkable abilities to convert mechanical energy into electric energy and vice versa. Advantages of the performance of the composites are discussed in the context of the orientation effects, first studied by the authors for main connectivity patterns and with due regard to a large anisotropy of effective piezoelectric coefficients and electromechanical coupling factors. The novelty of the book consists in the systematization results of orientation effects, the anisotropy of piezoelectric properties and their role in forming considerable hydrostatic piezoelectric coefficients, electromechanical coupling factors and other parameters in the composites based on either ferroelectric ceramic or relaxor-ferroelectric single crystals.

This book covers the topic of vibration energy harvesting using piezoelectric materials. Piezoelectric materials are analyzed in the context of their electromechanical coupling, heterogeneity, microgeometry and interrelations between electromechanical properties. Piezoelectric ceramics and composites based on ferroelectrics are advanced materials that are suitable for harvesting mechanical energy from vibrations using inertial energy harvesting which relies on the resistance of a mass to acceleration and kinematic energy harvesting which couples the energy harvester to the relative movement of different parts of a source. In addition to piezoelectric materials, research efforts to develop optimization methods for complex piezoelectric energy harvesters are also reviewed. The book is important for specialists in the field of modern advanced materials and will stimulate new effective piezotechnical applications.

Piezoelectric materials and shape memory alloys (SMAs) are very common materials for actuators and sensors; however their composites as electrical generators are least explored, although the use of piezoelectric materials as the mechanical energy harvester is becoming popular. In this dissertation piezoelectric material and SMA are used as constituents for an active composite of two types; one is a composite of piezoelectric material and SMA as an actuator and the second one is a composite as a thermal energy harvester. The analytical modeling and experimental study related to Piezo-SMA active composites are examined for both cases. Eshelby's inclusion problems are combined into a single model to treat the coupled behavior of electro-mechanics inherent in the piezo-SMA composite where the piezo is matrix phase and SMA is filler phase. SMA undergoes phase transformation such as stress-induced martensite transformation and temperature induced austenite transformation. Basic design and experimental work done on active composite are discussed in the areas of material characterization and mechanical modeling.

“Electromechanical Properties in Composites Based on Ferroelectrics” investigates the problem of prediction and non-monotonicity of the effective electromechanical (piezoelectric, dielectric and elastic) properties in two- and three-component composites based on ferroelectric ceramics and relaxor-ferroelectric single crystals. The book analyzes the interrelations between the electromechanical constants of the components, and describes the different analytical schemes for averaging the properties of these materials with different connectivity and microgeometrical characteristics. The book highlights the advantages of different methods for predicting the electromechanical properties and choosing the optimum components, and demonstrates the non-trivial behavior of specific composite architectures and the parameters of value for engineering applications. The book is of benefit to all specialists looking to understand the detailed behavior and electromechanical response of advanced composite materials.
