Power small devices more efficiently and practically with these essential materials Piezoelectric energy harvesting is an increasingly widely-deployed technique to generate electricity from mechanical energy. Reliability, ease of use, and cleanliness make piezoelectric energy harvesting in small electronic devices a potentially valuable alternative to the practical challenges and waste production of disposable or even reusable batteries. However, piezoelectric materials have their own challenges, advantages, and limitations, and choosing between them is a difficult engineering problem in itself; hybrid piezoelectric materials, which can be used to compensate the weaknesses of individual piezoelectric materials (like ceramic or polymer), are the emerging solution. Hybrid Materials for Piezoelectric Energy Harvesting and Conversion offers a systematic analysis of these hybrid piezoelectric materials and their applications. Each hybrid piezoelectric material is analyzed for its fundamentals, structural requirements, and applications, and the result is a significant contribution to materials science and electronic engineering. Hybrid Materials for Piezoelectric Energy Harvesting and Conversion readers will also find: * Comprehensive coverage of piezoelectric materials to provide the best fit for any set of engineering needs * Detailed discussion of inorganic, organic, and hybrid piezoelectric materials * Surface modification of piezoelectric filler in composite based piezoelectric materials * Importance of semiconductive and conductive materials in enhancing piezoelectric response of hybrid piezoelectric materials * In depth analysis of bio-based hybrid piezoelectric materials Hybrid Materials for Piezoelectric Energy Harvesting and Conversion is ideal for researchers in materials sciences, polymers, textiles, green and renewable energy, and all related fields.
