The increasing use of implants in the body for various therapeutic purposes has created a need to know the exact function of these implants while inside the body. This book highlights the recent advances in communication technologies, and discusses the development of implants that have the capacity to communicate with the outside world and inform care providers of the status of the implant. Health data collected from implants using such communication is of great importance to advancing research for a new generation of smart implants. This book explores how the control of implants remotely is also increasingly important, especially where intervention is needed, or if controlled release of active substances are required. The chapters cover types of implants where communication may be used, communication strategies, communication tools, powering, data acquisition, management and security, standardization, approvals, clinical translation, as well as current challenges and future research directions. This comprehensive book focuses specifically on communicating medical implants, thereby serving as a reference for basic scientists, electrical engineers, people working with sensors and communication technologies, information technology, healthcare providers, and clinicians.
