In this paper we demonstrate by computed examples that an array of sensors in nearfield configuration can provide source localization in both x and y, going beyond the usual directional localization provided by a 1-dimensional array. This ability to localize a source opens new application areas. An application presented here is the possibility of doing active noise cancellation of the sound of a snorer. © 2024 IEEE.

This paper presents a compact planar ultrawideband (UWB) band-pass filter (BPF). Initially, it employs a compact BPF with a reversible notched band to reject unwanted signals. The second phase entails determining and establishing the conventional microstrip feed's input impedance at a fixed value of 50 ohms. Then, to eliminate the unwanted signal, a triangle-shaped patch is etched from an L-shaped parallel linked transmission line. The bottom part of the BPF receives grounding. The BPF is designed, simulated, and fabricated in the laboratory. The measured fractional impedance bandwidth of 4.42 and 25.83%, minimum insertion loss of 1.40 and 0.32 dB, and minimum total loss of 15 and 8%, along with flat group delay at first and second resonant frequencies, respectively. Notably, BPF exhibits minimal loss, exceptionally low distortion, and acceptable speed. It demonstrates that the simulation and experimental results support the conclusions. The proposed BPF is suitable for S/C-band applications. © 2024 IEEE.

In this work, we present an alternative method for modeling finite-element magnetoinductive waveguides (MIWs) based on an equivalent circuit derivation. The proposed method provides practical insight into the behavior and operation of finite MIWs that cannot be fully explained using the dispersion model currently dominating MIW analysis, such as passband ripples. The model shows excellent agreement with simulated and experimental results when compared with first-order dispersion relation analysis and demonstrates the ability to predict behavior under complex MIW structures, such as junctions. To our knowledge, this is the first time that the equivalent circuit model presented in this work has been used to analyze MIW behavior and performance. © 2024 IEEE. All rights reserved.

Chronic diseases are the leading cause of death and disability worldwide, necessitating early detection and management to mitigate their adverse effects on health and improve quality of life. Leveraging machine learning algorithms has become a prominent approach in predicting the risk of various chronic diseases. These algorithms excel in analyzing complex datasets to identify patterns and risk factors associated with chronic conditions. This study explores the application of two different machine learning algorithms on an open-source dataset to predict the risk of chronic diseases. The outcomes of these implementations are analyzed and discussed in the final section, providing insights into their effectiveness and potential for enhancing chronic disease management. © 2024 IEEE.

Characterizing the susceptibility of an IC while it is integrated within a system can be challenging. Characterization is even harder if one wants to know the waveform at the target IC pin when injecting a signal on the pin. In this work, the feasibility of a direct injection probe with a capacitively coupled return and integrated voltage monitor is proposed. This probe is advantageous because it does not need to be soldered to the test device and its ability to provide a measurement of the waveform on the target IC pin during the injection. Methods for reconstructing the pin waveform based on probe measurements are discussed. Initial results indicate that the presented probe is generally insensitive to landing position variations and can accurately provide the waveform at the target IC during an injection. Future work is focused on further validation of the presented probe. © 2024 IEEE.

This study presents the development of a novel microfluidic device designed for non-invasive impedance spectroscopy assessment of mammalian embryos, with a focus on bovine embryos. The system is capable of gentle embryo manipulation using precisely controlled negative pressure. The microfluidic device includes adjustable electrodes for measuring electrical properties directly. It is also designed to facilitate embryo recovery after impedance measurements for immediate transfer into the mother. Simulations were performed to optimize the electrode size, with the aim of maximizing electrical current flow through the embryo. A decrease in the real component of the differential impedance at 1.49 MHz was observed and is correlated with the growth of the embryo's cell mass over time. © 2024 IEEE.

Stress has a severe impact on individuals irrespective of age, sex, work, or background. The reliable development of stress detection techniques enhances the social, educational, physical, economic, and professional quality of life, preventing chronic stress and proposing alleviation strategies. Research studies examine psychological, cognitive, behavioral, and physiological reactions to identify stress adequately. Deep Learning (DL) has received significant attention in recent years as it deals with high-dimensional, heterogeneous data and automatically learns representative features. This paper presents a survey on stress detection with recent DL approaches, leveraging data from all possible sources (physiological, speech, facial expressions, gestures, and social media content). The methodological outlines, the best results, and the main contributions of each study are discussed. We also describe publicly available datasets used by several of the presented works. Finally, we emphasize various open issues within the field of research and highlight key directions for future work © 2024 IEEE.

We introduce a novel wireless implant telemetry system that utilizes magnetoinductive waveguides (MIW) to break state-of-the-art boundaries in terms of: (a) transmission loss, and (b) bandwidth. Magnetoinductive waveguides rely on the careful design of a series of resonant loops, where excited current on the transmit loop leads to the current propagating as magnetoinductive waves to the receive loop. A MedRadio (401-406 MHz) MIW is shown to communicate with a 49.3 mm 3 implant at 1 cm dept. with a transmission loss of only 19.4 dB and a bandwidth of 187.4 MHz. This represents an improvement of over 30 dB and 85 MHz over a similar Radio-Frequency (RF) based system. Notably, the reported MIW framework empowers a full wearable system that can be integrated into clothing to handle wireless nodes placed both on and inside the human body. © 2023 ACES.

In this paper, a new pm-assisted model has been developed for the already introduced two-layer sub-harmonic synchronous machine. This work aims to increase the torque-producing capability of the brushless wound rotor machines while keeping the use of rare earth magnets to a minimum. A 2D finite element analysis has been performed to validate the proposed model and compare the performance with the reference model. The results in the paper demonstrate that the proposed machine's average torque has increased. © 2023 ACES.

We have previously demonstrated composites of polyaniline and cellulose acetate (PANI-CA) that bend with response to acetone gas and can be fused with electromagnetic-based resonant loops to quantify their bending. An example application lies in monitoring breath acetone as a biomarker of human metabolism. As would be expected, performance of the resulting sensor depends on the form size of the strip and loops. In this work, we explore such aspects using a numerical parametric study. Our results show that lower power requirements and, in certain cases, detection of bending by more than 160° is made possible simply by increasing the loop size or shortening the strip. However, the sensing dynamic range decreases significantly. These findings can be leveraged in the future to modify the chemo-actuators for better sensing capabilities. Concurrently, these results are generalizable for other applications that rely on thin film deformations. © 2023 IEEE.
