The textbook "Wireless Power Transfer for Medical Microsystems" offers a comprehensive introduction to the latest technologies for designing wireless power transfer systems for medical applications. The authors, Tianjia Sun, Xiang Xie, and Zhi-Hua Wang, present a systematic classification of the various types of wireless power transfer, with a focus on inductive energy coupling. The book addresses the challenges encountered in the development of wirelessly operated implants, such as the efficiency of energy transfer, the stability of power supply, and the size of energy antennas and circuits. By focusing on medical applications, real systems, such as a battery-free capsule endoscopy system, are used as examples of the techniques described. This detailed analysis is particularly valuable for professionals and students engaged in the development of innovative medical technologies.
