To conclude, we have given an introduction to the wireless power transfer for biomedical applications in  Chap. 1. By developing the wireless power transfer, researchers hope to provide biomedical devices with more power, longer operating time, smaller system size, and safer insurance.  Chapter 2 has presented the systematic design for typical transfer systems. The working principles, classifications, systematic design considerations, and safety concerns were introduced. From  Chaps. 3,  4,  5, we have illustrated many designs regarding power antennas, power converters, and power management. By using them, two design cases have been proposed in  Chap. 6 for the batteryless capsule endoscopy. In the final chapter, we are going to review the work we have introduced. Moreover, we would look into future and summarize major challenges in the future.
