An improved wireless power transfer system with adaptive technique for Implantable Biomedical Devices

Modern medical treatment and diagnoses benefit from IT technologies ranging from small pill transceiver devices to permanent implanted devices. Either case must communicate to the external devices for the medical expert to view. Moreover, these devices require certain form of power supply in order for the device the function properly. In order to minimize the necessary battery requirement, power consumption per bit and required internal battery cell is carefully designed. Among the choices for power supply arrangement, wireless power transfer (WPT) technology is providing an alternative promising solution for supplying power to medically implanted devices. In this paper, WPT technology for medically implantable device is analyzed. Some of the issue is studied, and possible solution is presented.
