Implantable medical devices (IMDs) are critically requested for the survival of patients subject to certain serious diseases such as bradycardia, fibrillation, diabetes, and disability, etc. Appropriate working of an active implantable medical device (IMD) heavily relies on the continuous supply of electricity. In this sense, longterm powering and recharging of an IMD via a highly safe, efficient and convenient way is, therefore, extremely important in clinics. Several conventional batteries, such as lithium cell, nuclear cell and bio-fuel cell, etc., have been developed to power IMDs. Meanwhile, the recharge of IMD from outside of the human body is also under investigation. In this paper, some of the most typical IMD batteries are reviewed. Their advantages and disadvantages are compared. In addition, several emerging innovations to recharge or directly drive the implanted batteries, including electromagnetic energy transmission, piezoelectric power generation, thermoelectric devices, ultrasonic power motors, radio frequency recharging and optical recharging methods, etc., are also discussed. Some fundamental and practical issues thus involved are summarized, and future prospects in this area are made.

The first part of this paper reviews the current development and key issues on implantable multi-sensor devices for in vivo theranostics. Afterwards, the authors propose an innovative biomedical multisensory system for in vivo biomarker monitoring that could be suitable for customized theranostics applications. At this point, findings suggest that cross-cutting Key Enabling Technologies (KETs) could improve the overall performance of the system given that the convergence of technologies in nanotechnology, biotechnology, micro&nanoelectronics and advanced materials permit the development of new medical devices of small dimensions, using biocompatible materials, and embedding reliable and targeted biosensors, high speed data communication, and even energy autonomy. Therefore, this article deals with new research and market challenges of implantable sensor devices, from the point of view of the pervasive system, and time-to-market. The remote clinical monitoring approach introduced in this paper could be based on an array of biosensors to extract information from the patient. A key contribution of the authors is that the general architecture introduced in this paper would require minor modifications for the final customized bio-implantable medical device.

This study proposes a direct‐current (DC) driving impedance matching method for rectennas for the wireless charging of implantable lithium‐ion (Li‐ion) rechargeable batteries using the medical implant communication service band. Unlike the traditional method, which uses only the DC resistive load or battery potential, the proposed method adopts the output DC current of the dual‐diode rectifiers to establish a simple equivalent model for wireless battery charging. Using this model, the optimised impedance matching network of the rectenna is derived to maximise efficiency within the charging range of a Li‐ion battery. For 10 dBm input radio‐frequency (RF) power, the highest RF‐to‐DC conversion efficiency of the traditional matching method is 22.3%. For the proposed method, the RF‐to‐DC conversion efficiency is > 75% in the potential range of 3.7 to 4.2 V, which is the range used for over 90% of the charging duration. The best battery charging efficiency was 76.2% at a transmission distance of 50 cm.
