Wireless Power Transfer for Medical Microsystems

Abstract

In this chapter, we will propose two design cases. They both are target to the wirelessly powered capsule endoscopy. The wireless power transfer helps improving the performance of the capsule endoscopy in terms of operating time and number of images. Comparing to other implantable devices like neural recorders and electrical stimulators, the capsule dynamically moves in digestive track. So, the transfer efficiency results in a broad range. In other words, the batteryless capsule endoscopy is actually a relatively complex biomedical application. The two design cases proposed in this chapter have different features and design considerations. In the first case, the wireless power is transferred from a floor to the capsule to allow patients walking freely in an inspection room. In the second case, the wireless power is transferred from a specially designed jacket to the capsule to allow patients going back home comfortably.
