“…For implants relatively close to the skin, infrared optical signal transmission has also shown promise. 216,217 Alternatively, custom radio frequency transmission protocol and antenna development can be pursued. A key consideration here is the propagation of electromagnetic signals through the human body.…”

Implantable sensors have revolutionized the way we monitor biophysical and biochemical parameters by enabling real-time closed-loop intervention or therapy. These technologies align with the new era of healthcare known as healthcare 5.0, which encompasses smart disease control and detection, virtual care, intelligent health management, smart monitoring, and decision-making. This review explores the diverse biomedical applications of implantable temperature, mechanical, electrophysiological, optical, and electrochemical sensors. We delve into the engineering principles that serve as the foundation for their development. We also address the challenges faced by researchers and designers in bridging the gap between implantable sensor research and their clinical adoption by emphasizing the importance of careful consideration of clinical requirements and engineering challenges. We highlight the need for future research to explore issues such as long-term performance, biocompatibility, and power sources, as well as the potential for implantable sensors to transform healthcare across multiple disciplines. It is evident that implantable sensors have immense potential in the field of medical technology. However, the gap between research and clinical adoption remains wide, and there are still major obstacles to overcome before they can become a widely adopted part of medical practice.

This article presents a review of different types of miniaturized rectenna integrated circuits IC used for energy harvesting applications such as medical applications. The rectenna design consists of two basic components: an embedded antenna that collects radio-frequency RF energy from the surrounding environment, and the rectifier circuit that converts AC-RF energy values into DC voltage for usage in low-power electronics devices such as implantable medical devices (IMDs). Microwave Schottky diodes HSMS-285x and SMS-763x series are used as a voltage doubler rectifier with an implanted antenna to improve conversion efficiency and the output voltage at a given input power and appropriate load.There are many challenges in the implantable rectenna IC design such as biocompatibility, miniaturization, patient safety, compact size, resonant frequency, bandwidth, radiation efficiency, and insensitivity to detuning. This review article summarizes the overall rectenna research carried out for new different design strategies in implant medical applications that operated at industrial scientific, and medical (ISM) bands such as 2.45GHz and 5.8GHz.

In this paper, a narrowband and compact antenna resonating at 6.1 GHz with a peak realized gain of 3.3 dBi is proposed to monitor the glucose concentration in the blood without taking invasive blood samples. The proposed antenna is fabricated using a low-cost FR-4 substrate with compact dimensions of 30 mm × 30 mm × 1.6 mm. The impedance bandwidth of this antenna ranges from 5.2 to 7.1 GHz. For measuring blood glucose levels, a human finger phantom model with dimensions of 15 mm × 12 mm × 10 mm is constructed using the EM simulation (HFSS) environment. The finger phantom consists of different layers such as skin, fat, muscle, blood, and bone modeled at 6.1 GHz using various dielectric materials for various glucose concentrations. The finger phantom model is placed at different locations around the antenna to measure the frequency shift for monitoring glucose concentration in blood samples. The proposed finger phantom model is validated by conducting an experimental study by placing a real human finger around the fabricated antenna and measuring the frequency shift. This study shows a very good agreement with the results obtained by the simulated phantom model. The advantages and outperformance of the proposed sensor are highlighted in terms of the sensitivity obtained and compared with other techniques given in the literature.
