“…In [85], precise extraction of fine-grained cardiogram waveforms was achieved using a parameterized respiratory filter (PRF) to accurately filter out respiratory motion. Moreover, the clinical experiment was conducted at the bedside in a hybrid operation theatre (OT) of the hospital to verify the performance of the proposed system, as shown in Fig.…”

“…One approach involves estimating the heart rate from radar signals within a short time window and then using the variations in heart rate to approximate HRV parameters [91], [92]. The second approach adheres to the medical definition of the RR interval, identifying waveforms in the radar demodulation signals that correspond to the QRS complexes in the electrocardiogram for precise RRI calculations [93], [94], [95].…”

“…One application was the first smartphone with a microwave radar inside [211]. The effectiveness of a radar system for Doppler Cardiogram (DCG) has been clinically validated to provide diagnostic information for heart diseases that contained abnormal activities with non-invasive, continuous blood pressure sensing, and the detection of heart failure, atrial fibrillation (AF) and premature heartbeat (PHB) [212], [213], [214].…”

Advances and updates in medical applications utilizing microwave techniques and technologies are reviewed in this paper. The article aims to provide an overview of enablers for microwave medical applications and their recent progress. The emphasis focuses on the applications of microwaves, in the following order, for 1) signal and data communication for implants and wearables through the human body, 2) electromagnetic energy transfer through tissues, 3) noninvasive, remote or in situ physical and biochemical sensing, and 4) therapeutic purposes by changing tissue properties with controlled thermal effects. For signal and data communication and wireless power transfer, implant and wearable applications are discussed in the categories of pacemakers, endoscopic capsules, brain interfaces, intraocular, cardiac and intracranial pressure sensors, neurostimulators, endoluminal implants, artificial retina, smart lenses, and cochlear implants. For noninvasive sensing, remote vital sign radar, biological cell probing, magnetic resonance and microwave imaging, biochemical, blood glucose, hydration and biomarker sensing applications are introduced. For therapeutic uses, the developments of microwave ablation, balloon angioplasty, and hyperthermia applications are reviewed. The scopes of this article mainly concentrate on the research and development efforts in the past 20 years. Recent review articles on specific topics are cited with accomplishment highlights and trends deliberated. At the end of this article, a brief history of the IEEE Microwave Theory and Techniques Society (MTT-S) Biological Effects and Medical Applications committee and the contributions by its members to the promotion and advancement of microwave technologies in medical fields are chronicled.
