About the Author
Jing‐Feng Li is Changjiang scholar distinguished professor of the School of Materials Science and Engineering at Tsinghua University, Beijing, China, and also serves as deputy director of Tsinghua University‐Toyota Research Center. Dr. Li has received master and doctor degrees in materials science and engineering both from Tohoku University (Japan) in 1988 and 1991 and a bachelor of engineering from Huazhong University of Science and Technology, China, in 1984. After temporarily working at Nihon Ceratec Co. Ltd., he was appointed to assistant professor in Tohoku University in 1992 and promoted to associate professor in 1997, then joined Tsinghua University as full professor in 2002. He also served as vice department chair (2005–2012) and vice school dean (2013–2016) of Materials of Materials Science and Engineering Department/School at Tsinghua University.
Dr. Li has conducted a wide range of research. His early work in Tohoku University focused on phase transition of zirconia ceramics, ceramic processing, and mechanical properties of silicon carbide and aluminum nitride ceramics, and ceramic microfabrication processing. From 2002 at Tsinghua, Li has been leading a research group with research interests on lead‐free ferroelectric ceramics for piezoelectric and energy storage applications, piezoelectric films for microelectromechanical system (MEMS) applications, thermoelectric materials, and microdevices for energy conversion, MEMS‐based microfabrication processing. He has published >490 papers (H‐index = 67) in prestigious journals and received several awards including distinguished young researcher award from the Japan Institute of Metals and the first‐class science and technology award from the Chinese Ceramic Society, distinguished young scholars fund from National Natural Science Foundation of China, Journal of the American Ceramic Society Loyalty Award.
He serves as Editor‐in‐Chief of Journal of Materiomics, associate Editor‐in‐Chief for Journal of the Chinese Ceramic Society, Reginal/Subject Editor for Journal of Materials Processing Technology (2005–2013), and editorial board member for NPG Asia Materials, Journal of Advanced Ceramics, Journal of Asian Ceramic Societies, Science China Technological Science, Energy Harvesting and Systems, Journal of Inorganic Materials, Electronic Components and Materials (Chinese), Powder Metallurgy Technology (Chinese). He has been elected to the President of Thermoelectric Materials and Applications Subsociety of Chinese Materials Research Society and Vice President of Micro/Nano Technology Subsociety of Chinese Ceramic Society in 2018. He is a fellow of the American Ceramic Society, board member of International Thermoelectric Society, full member of International Institute for the Science of Sintering, and ferroelectric committee member of IEEE Ultrasonics, Ferroelectrics, and Frequency Control Society.
Foreword by Professor Longtu Li
Piezoelectric materials possess the functionality of interconversion between electrical energy and mechanical energy, which have been widely used in electronic information, communication, automobile, military defense, aeronautics and space technology, medical diagnostics, energy storage and harvesting, artificial intelligence, and advanced manufacturing, among other applications. The market‐dominating piezoelectric ceramics are based on the Pb(Zr,Ti)O3 (abbreviated as PZT) system, which is a big family with diverse chemical modifications designed for specific applications. PZT‐based ceramics possess comprehensive excellent properties, but its environmental incompatibility has generated increasing concerns since the beginning of the twenty‐first century. In addition, the European Union's legislation about Restriction of the use of certain Hazardous Substances (RoHS) in electrical and electronic equipment has accelerated the research and development of high‐performance lead‐free piezoelectric ceramics.
Piezoelectric ceramics and device applications have been one of the key research directions in the State‐Key Laboratory of New Ceramics and Fine Processing, Tsinghua University. At Tsinghua University, our research groups mainly focused
