Advances in medical technology and promote the human implantable wireless energy transfer devices are widely used. Traditional human implantable wireless energy transfer device have some problems of low charging efficiency, blindly charging and data transmission difficult. On the basis of the conventional electromagnetic induction, in this paper, we proposed the use of magnetically coupled resonant way on human implantable device for charging, this method can greatly improve the efficiency of wireless charging. The system gets the CPU’s unique ID of human implantable devices to identifying the device. We can artificially control human implantable device’s charging device number, so as to solve the problems caused by the blind charge. Meanwhile, the system uses an electromagnetic carrier approach for data transmission, both to simplify the complexity of hardware devices and improve the communication efficiency of the device.

The working principle of half-bridde Class D Parallel-Resonant Inverter (PRI) as power amplifier is presented in this paper. Simulation of the model is carried out using Proteus.  In order to verify the simulation results, an experimental verification is done. This inverter is used to excite the PZT transducers at the suggested resonant frequency of 416 kHz with power level transferred through Acoustics Energy Transfer (AET) concept at about 80mW. As experimental outcome result, the system managed to transfer energy at 66mW to the receiver side.

This chapter will discuss the various energy-based modalities that are available to optimize circumferential trunk liposuction to enhance patient results. We will discuss multimodal liposuction using power assisted liposuction, ultrasonic energy addition, as well as radiofrequency assisted modalities to achieve adipose reduction and concurrent skin and soft tissue contraction. An in-depth look at patient selection and intraoperative technique will be presented. The postoperative management for each modality will be discussed in detail, including expected results from each modality and potential complications and their ensuing management. We will also discuss the application of different modalities alone and in combination to achieve superior results.

Acoustic energy transfer (AET) technology has drawn significant industrial attention recently. This paper presents the reviews of the existing AETs sequentially, preferably, from the early stage. From the review, it is evident that, among all the classes of wireless energy transfer, AET is the safest technology to adopt. Thus, it is highly recommended for sensitive area and devices, especially implantable devices. Though, the efficiency for relatively long distances (i.e., >30 mm) is less than that of inductive or capacitive power transfer; however, the trade-off between safety considerations and performances is highly suitable and better than others. From the presented statistics, it is evident that AET is capable of transmitting 1.068 kW and 5.4 W of energy through wall and in-body medium (implants), respectively. Progressively, the AET efficiency can reach up to 88% in extension to 8.6 m separation distance which is even superior to that of inductive and capacitive power transfer.
