Ultrasound Energy and Data Transfer for Medical Implants

This book presents new systems and circuits for implantable biomedical  applications, using a non-conventional way to transmit energy and data  via ultrasound.  The authors discuses the main constrains (e.g. implant  size, battery recharge time, data rate, accuracy of the acoustic models)  from the definition of the ultrasound system specification to the  in-vitro validation.The system described meets the safety requirements  for ultrasound exposure limits in diagnostic ultrasound applications,  according to FDA regulations.  Readers will see how the novel design of  power management architecture will meet the constraints set by FDA  regulations for maximum energy exposure in the human body.  Coverage  also includes the choice of the acoustic transducer, driven by optimum  positioning and size of the implanted medical device. Throughout the  book, links between physics, electronics and medical aspects are covered  to give a complete view of the ultrasound system described.

Provides a complete, system-level perspective on the use of ultrasound as energy source for medical implants;
Discusses  system design concerns regarding wireless power transmission and  wireless data communication, particularly for a system in which both are  performed on the same channel/frequency;
Describes an experimental study on implantable battery powered biomedical systems;
Presents a fully-integrated, implantable system and hermetically sealed packaging.
