“…Therefore, reducing power consumption in these devices is crucial for extending the battery's lifespan. One promising approach to reduce power usage is by optimizing computational requirements using specialized "algorithms" [65][66][67] or designing special chips that can process medical data efficiently while minimizing energy consumption [68][69][70]. Furthermore, this cluster also investigates keywords related to "IoT."…”

In the present era of advanced medical technology, there has been a significant increase in the utilization of wireless-based implantable medical devices (IMDs) in various biomedical applications, including health diagnosis, monitoring, recording, treatment, and other clinical concerns. It is essential to closely examine the research trends in wireless IMD topics to understand their growth trajectory. This can be achieved through the utilization of bibliometric reviews. While there are numerous experimental studies and survey papers on the topic, there is a dearth of review papers that utilize a bibliometric approach. Therefore, this study aims to conduct a bibliometric analysis to identify emerging research trends in wireless IMDs for biomedical applications for the first time. An analysis was conducted on 1,650 articles retrieved from the Scopus database from its inception until September 2023. The study used tools such as VOS Viewer to measure performance and science map parameters, and Tableau Cloud to visually enhance the analysis process. This research endeavor allowed us to analyze historical trends, influential papers, top journals, institutions, countries, and authors within this field. The top three influential journals in this field are IEEE Transactions on Biomedical Circuits and Systems, IEEE Transactions on Antenna and Propagation, and IEEE access. The National University of Singapore is the most productive institution in terms of overall publications. The United States, China, and India make significant contributions to overall publications. Finally, we also examined the most significant keywords and current research areas within this field.

“…Shan et al designed and prepared a monolithic wireless battery-free neural recorder with an integrated flexible antenna, which has been successfully implanted. [81] The device consisted of a flexible antenna and a self-powered complementary metal-oxide-semiconductor chip, which was capable of being wirelessly powered at a distance of 16 cm from the flexible antenna at a frequency of 915 MHz. The implementation of current wireless power transfer (WPT) configurations in dynamic environments is hampered by their restricted operating area and susceptibility to changes in operating conditions.…”

“…In the mouse experiments, this device demonstrated a response to visual stimuli. [81] As the device only weighed 0.43 g and was feather-soft, the apparatus did not restrict the mice's ability to move while the experiment was being conducted. Kim et al also developed a highly flexible ECoG microelectrode array on parylene films using a fast, low-cost, mask less versioning inkjet printing technique.…”

Flexible sensors, as a significant component of flexible electronics, have attracted great interest the realms of human–computer interaction and health monitoring due to their high conformability, adjustable sensitivity, and excellent durability. In comparison to wearable sensor‐based in vitro health monitoring, the use of implantable flexible sensors (IFSs) for in vivo health monitoring offers more accurate and reliable vital sign information due to their ability to adapt and directly integrate with human tissue. IFSs show tremendous promise in the field of health monitoring, with unique advantages such as robust signal reading capabilities, lightweight design, flexibility, and biocompatibility. Herein, a review of IFSs for vital signs monitoring is detailly provided, highlighting the essential conditions for in vivo applications. As the prerequisites of IFSs, the stretchability and wireless self‐powered properties of the sensor are discussed, with a special attention paid to the sensing materials which can maintain prominent biosafety (i.e., biocompatibility, biodegradability, bioresorbability). Furthermore, the applications of IFSs monitoring various parts of the body are described in detail, with a summary in brain monitoring, eye monitoring, and blood monitoring. Finally, the challenges as well as opportunities in the development of next‐generation IFSs are presented.

There is a widely shared and potentially well-justified enthusiasm for autonomous field-deployed (FD) wearable, implantable, and environmental sensors for the continuous monitoring of a variety of chronic conditions, such as diabetes, depression, irritable bowel syndrome, and soil nitrate depletion. These FD sensors are often viewed as miniaturized versions of laboratory-based or point-of-care (POC) biosensors, with the primary focus being on material development and mechanical form factor challenges (e.g., stretchability, flexibility, and biocompatibility). In this article, we highlight that the FD sensors are fundamentally different compared to lab-based or POC sensors. We borrow concepts from biology (e.g., bacteria) to quantify the fundamental challenges inherent to such sensors and strategies to overcome them.
