“…[ 200 ] Nevertheless, the evident drawback of this linear scheme is vulnerable to noise due to the carrier amplitude is easily corrupt by the interference. [ 204 ] Therefore, the probability of BER in OOK is higher than that of FSK and PSK, [ 203 ] where BER is defined as the ratio of the number of bit errors to the total received bits. The noise immunity of a data link is measured by BER versus signal‐to‐noise ratio (SNR).…”

Cardiovascular disease continues to be one of the dominant causes of global mortality. One effective treatment is to utilize cardiovascular implantable devices (cIMDs) with multi‐functional cell sensing and monitoring features that have the potential to manipulate cardiovascular hyperplasia disorders as well as provide therapy. However, batteries with a fixed capacity entail high‐risk surgeries for battery‐replacement, which causes health hazards and imposes significant costs to patients. This review accesses comprehensive power solutions for cIMDs, from conventional batteries to state‐of‐the‐art energy harvesters and wireless power transfer (WPT) schemes. In particular, WPT has great potential to eliminate the percutaneous wires and overcome frequent battery removal. Here, the fundamentals, power transfer efficiency, antenna design and miniaturization, and operating frequencies in various WPT schemes are presented. Moreover, the power loss attenuation and bio‐safety standard (specific absorption rate) for implants are also considered in WPT design envelope. In addition, wireless data transmission of implantable devices from external to internal milieu (and vice versa) along with different modulation and demodulation techniques are investigated. The last advanced power solutions for cIMDs in in‐vivo and in vitro research are illustrated throughout. Finally, specifications and future potential of WPT systems in cIMDs are highlighted.

“…The preliminary research in this review paper shows that HGNS is a considerable prospect because of its high cure rate; it also has lower operational complexity than other surgical methods and does not need to remove redundant tissues. With the development of implantable medical devices based on a wireless power source and data transmission embedded in a smart electronic system in the human body for monitoring and treatment purposes [128]. HGNS will become smarter and more efficient in the future.…”

Obstructive sleep apnea (OSA), a common sleep disorder disease, affects millions of people. Without appropriate treatment, this disease can provoke several health-related risks including stroke and sudden death. A variety of treatments have been introduced to relieve OSA. The main present clinical treatments and undertaken research activities to improve the success rate of OSA were covered in this paper. Additionally, guidelines on choosing a suitable treatment based on scientific evidence and objective comparison were provided. This review paper specifically elaborated the clinically offered managements as well as the research activities to better treat OSA. We analyzed the methodology of each diagnostic and treatment method, the success rate, and the economic burden on the world. This review paper provided an evidence-based comparison of each treatment to guide patients and physicians, but there are some limitations that would affect the comparison result. Future research should consider the consistent follow-up period and a sufficient number of samples. With the development of implantable medical devices, hypoglossal nerve stimulation systems will be designed to be smart and miniature and one of the potential upcoming research topics. The transcutaneous electrical stimulation as a non-invasive potential treatment would be further investigated in a clinical setting. Meanwhile, no treatment can cure OSA due to the complicated etiology. To maximize the treatment success of OSA, a multidisciplinary and integrated management would be considered in the future.

“…Wireless power transfer (WPT) and data transfer can eliminate the need for bulky batteries and wires and support significant scaling of future IMDs with extended lifetime. When considering modern implants of more than 64 electrodes, recording local field potentials and neural spikes with a sampling rate higher than 10kS/s and a resolution of at least 8 bits, power levels greater than 100 mW with data rates in excess of 5 Mbps are required [41]. Inductive coupling has been the dominant technique to support wireless powering over short distances (10-20mm) over the last decades.…”
