In this work, we propose several solutions to overcome these challenges. Firstly, we designed a metamaterial-inspired transmitter (TX) based on a multi-ring resonator (MRR). This transmitter achieves low magnetic loss and is used as a director to supply power to the RX, featuring an integrated uncomplicated matching circuit rectifier. Secondly, to realize the rectifier, we leverage the high coupling achieved through the proposed MRR metamaterial. The rectifier is integrated on the backside of the RX substrate without requiring additional area for further compactness. Additionally, we introduce a metamaterial-based isolator designed to reduce magnetic field leakage on the back side of the system. Importantly, this isolator has been proven to have no adverse effects on the original wireless power transfer (WPT) system's performance. A prototype was successfully fabricated, and both RF-dc simulation and measurements indicate a peak efficiency of 43% and 39%, respectively, at 50 MHz for a 9 mm embedded RX in chicken breast tissue. The TX size is 20 mm × 20 mm, while the integrated RX/rectifier has dimensions of 7 mm × 7 mm.","PeriodicalId":29955,"journal":{"name":"IEEE Journal of Electromagnetics RF and Microwaves in Medicine and Biology","volume":"8 2","pages":"144-154"},"PeriodicalIF":3.2,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141084776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact of a fall can vary from minor bruises, to life altering fractures and even become fatal. The purpose of this study is to establish a novel non-contact radar method of detecting an elderly fall when occurred in home staying. The novelty of the proposed detection technique is the exploitation of a 1D effective acceleration derived from Short Time Fourier Transform (STFT). This technique was tested utilizing a 2.45 GHz Continuous Wave (CW) Radar implemented with a Software Defined Radio (SDR) and low-cost, off-the-shelf components. Herein, we present test results that classify incidents as either falls or non-falls in line-of-sight cases. Firstly, the results are compared with the corresponding values measured with a commercial marker-based optoelectronic motion capture multi-camera system (VICON) showing high similarity. Furthermore, real-time scenarios were conducted to estimate the accuracy and the number of false alarms of the proposed method. The proposed algorithm is proved capable of exploiting the Power Burst Curve (PBC) as a preliminary factor to yield an efficient fall incident classifier based on the effective acceleration, while minimizing the required processing resources.","PeriodicalId":29955,"journal":{"name":"IEEE Journal of Electromagnetics RF and Microwaves in Medicine and Biology","volume":"8 2","pages":"102-112"},"PeriodicalIF":3.2,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10459050","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141084875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic resonance human body communication (MR HBC) provides ideas to improve the transmission effect. Although the coil's resonance properties have been proposed for MR HBC, the modeling and impedance matching for this method are still in the exploratory stage. However, different human impedances affect the coil resonance frequency to varying extents, leading to individual variability in the degree of magnetic coupling. This paper analyzes the influence of human tissues on the coil through finite element method (FEM) simulation modeling. This effect can be eliminated by employing a dual tunable capacitor matching method based on the field-circuit combination. By dynamically adjusting the values of the dual tunable capacitors in real-time, the human body and the coil can be tuned to a resonant state, effectively improving the degree of magnetic coupling. The results reveal that the proposed method enhances the communication gain by 38.91–42.02 dB at the preset frequency for different human tissues. In vivo experiments verify that the method eliminates the effect of different human impedances on the coil, which is of great significance for further improving the performance of MR HBC.","PeriodicalId":29955,"journal":{"name":"IEEE Journal of Electromagnetics RF and Microwaves in Medicine and Biology","volume":"8 2","pages":"94-101"},"PeriodicalIF":3.2,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141084921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leakage may also be relevant to implanted stent grafts for the treatment of abdominal aneurysms. Indeed, blood may leak through the stent into the aneurysm sac with the risk of rupture due to increased internal pressure. As standard screenings cannot be performed frequently enough, this paper proposes wireless monitoring of fluid leaks into human body regions exploiting an implanted antenna partially coated by an engineered material and an auto-tuning IC in the UHF RFID band. The presence of fluid modifies the antenna impedance in a controlled way by the hydrolysis of the coating. An indication of this change can be obtained through radiofrequency interrogation from an external reader even when the antenna is implanted at 6 cm. Simulations and tests with a mock-up demonstrated the ability to distinguish the degradation of the bioresorbable coating.
