Omnidirectional Inductive Powering for Biomedical Implants
investigates the feasibility of inductive powering for capsule endoscopy
and freely moving systems in general. The main challenge is the random
position and orientation of the power receiving system with respect to
the emitting magnetic field. Where classic inductive powering assumes a
predictable or fixed alignment of the respective coils, the remote
system is now free to adopt just any orientation while still maintaining
full power capabilities. Before elaborating on different approaches
towards omnidirectional powering, the design and optimisation of a
general inductive power link is discussed in all its aspects. Special
attention is paid to the interaction of the inductive power link with
the patient's body. Putting theory into practice, the implementation of
an inductive power link for a capsule endoscope is included in a
separate chapter.
