The force-frequency characteristics of AT-cut strip quartz crystal resonators (QCRs) were investigated in this paper by combining finite element analysis with experimental data. We conducted a finite element analysis with COMSOL Multiphysics software to determine the stress distribution and particle displacement characteristics of the QCR. Furthermore, we investigated the influence of these counteracting forces on the frequency shift and stresses experienced by the QCR. An experimental study was performed to determine how the resonant frequency, conductance, and quality factor (Q value) of three AT-cut strip QCRs, rotated by 30, 40, and 50 degrees, change in response to different force application points. The results indicated that the QCR frequency shifts scaled in direct proportion to the force's magnitude. QCR's rotational sensitivity measurements showed the strongest response at 30 degrees, a decrease at 40 degrees, and the lowest response at 50 degrees. The effect of the force-applying location's distance from the X-axis was evident in the frequency shift, conductance, and Q-factor of the QCR. To understand the force-frequency characteristics of strip QCRs with different rotation angles, this paper's results are highly informative.

The widespread transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing Coronavirus disease 2019 (COVID-19), has created difficulties in effectively diagnosing and treating chronic illnesses, leading to potential long-term health complications. This worldwide crisis sees the pandemic's ongoing expansion (i.e., active cases), alongside the emergence of viral variants (i.e., Alpha), within the virus classification. This expansion consequently diversifies the correlation between treatment approaches and drug resistance. Consequently, the assessment of patient condition incorporates healthcare data, which includes symptoms like sore throats, fevers, fatigue, coughs, and shortness of breath. Unique insights are attainable through the use of wearable sensors implanted in a patient, which produce periodic analysis reports of the patient's vital organs for a medical center. In spite of that, predicting the risks and the countermeasures to address them is still a formidable challenge. In light of this, this paper proposes an intelligent Edge-IoT framework (IE-IoT) for the purpose of early detection of potential threats (including behavioral and environmental factors) in diseases. This framework's primary goal is to utilize a novel, pre-trained deep learning model, empowered by self-supervised transfer learning, to construct a hybrid learning model using an ensemble approach, and to provide a thorough evaluation of predictive accuracy. A thorough analysis, similar to STL, is vital for establishing proper clinical symptoms, treatments, and diagnoses, by evaluating the effects of learning models such as ANN, CNN, and RNN. Experimental data supports the observation that the ANN model successfully incorporates the most pertinent features, achieving a considerably higher accuracy (~983%) than alternative learning models. Through the use of IoT communication technologies including BLE, Zigbee, and 6LoWPAN, the proposed IE-IoT system can assess power consumption. The real-time analysis indicates that the proposed IE-IoT, which uses 6LoWPAN, is significantly more efficient in terms of power consumption and response time compared to existing solutions for the early detection of suspected victims of the disease.

Unmanned aerial vehicles (UAVs) have been employed to expand communication coverage and facilitate wireless power transfer (WPT) in energy-constrained communication networks, effectively prolonging their service life. The matter of how to optimally guide a UAV's movement in such a system remains a significant issue, particularly given its three-dimensional form. Employing a UAV-mounted energy transmitter for wireless power transfer to multiple ground energy receivers was examined in this paper as a solution to the problem. Maximizing the energy harvested by all energy receivers during the mission period was achieved by meticulously optimizing the UAV's three-dimensional flight trajectory, aiming for a balanced trade-off between energy consumption and wireless power transfer performance. The following detailed designs served as the cornerstone of the accomplishment of the established goal. Research from earlier studies indicates a direct correlation between the UAV's abscissa and altitude. This work, thus, concentrated on the height versus time aspect to identify the optimal three-dimensional flight path for the UAV. Instead, the method of calculus was applied to the calculation of the total accumulated energy, ultimately producing the proposed high-efficiency trajectory design. The simulation's final results indicated that this contribution has the potential to bolster energy provision by carefully formulating the UAV's 3D flight path, as opposed to more conventional approaches. The contribution discussed above presents a promising prospect for UAV-enabled wireless power transmission in the future Internet of Things (IoT) and wireless sensor networks (WSNs).

To measure the phase shift produced by the glucose-glucose oxidase (GOx) chemical reaction, we developed a glucose fiber sensor using heterodyne interferometry. Both experimental and theoretical studies revealed a reciprocal relationship between glucose concentration and phase variation. A linear measurement scale for glucose concentration, from 10 mg/dL to 550 mg/dL, was a feature of the proposed method. The experimental results indicate that the length of the enzymatic glucose sensor is a critical determinant of its sensitivity, yielding optimal resolution at a length of 3 centimeters. The optimal resolution obtained through the proposed method is greater than 0.06 mg/dL. The suggested sensor, in addition, demonstrates excellent consistency and reliability. The average relative standard deviation (RSD) is well above 10%, conforming to the necessary specifications for point-of-care devices.
