In the advanced world that we have today, it is important for consumers to have devices that are smaller in size and are easily available, and should be powerful in terms of specifications and performance. Also, there is a demand for the industries to miniaturize the parts as smaller as possible in order to meet the consumer requirements. A sensor is a key element in any automated system/device as it senses the physical changes in the environment and processes this data. Thus, paving way for smart sensors which have revolutionized the tech industry by their ability to consist an entire data conversion and processing units on a single chip or the System on Chip (SoC). The presented review paper describes about the research survey performed on sensors, transducers, and also on the evolving smart sensor technology which helped in innovating the state-of-the-art sensor technology such as the smart dust. A detailed study on the smart dust sensor technology and its capabilities to sense physical phenomena such as sound, vibration, temperature, light, magnetism, acceleration, position, stress, humidity, and chemical traces has been analyzed. At present, the smart dust sensor technology is under critical research, testing, and prototyping process. Furthermore, the future scope of the smart dust or mote technology is discussed by the describing the need for these sensors in various fields and also by showing the graphical representation of the Gartner’s hype cycle. The paper concludes by presenting the important aspects of a smart dust sensor, its usability, necessity, and also estimating the impact of this sensor technology in the rapid advancement of the tech industry.

Erroneous determination of blood glucose concentration in patients with diabetes can lead to errors in treatment. To prescribe the correct and non-traumatic treatment to the patient, you need to increase the accuracy of determining the concentration of glucose in the patient's blood. The authors of the article suggest the use of adaptive statistical methods to improve accuracy, which work well with a small number of repeated measurements under conditions of uncertainty of external factors. Such methods have proven themselves well in various fields of science and technology, where precise control of a large group of measurements is required. Such statistical methods have been well studied in terms of mathematics and applied in high-precision manufacturing. They allow you to adjust the required dose of the injected substance on the basis of several previous measurements in order to exclude insufficient or excessive administration. Both of these cases - an insufficient and excessive amount of the drug - lead to an incorrect glucose content in the patient's blood (hypo- and hyperglycemia), and have a bad effect on further treatment. To exclude such cases and improve the quality of treatment and the future life of patients with diabetes mellitus, a solution method using statistics is proposed.

Objective: This study aimed to develop and evaluate a 3-degree-of-freedom (DoF) robotic system for the safe delivery of cardiac sheaths through challenging anatomical structures, including the fossa ovalis and pathways with tight curves. Methods: The robot and its kinematic model were built on a previously proposed single-DoF actuation module and bending model. A sheath delivery strategy (SDS) was developed, combining two control methods: tip position control to approach an optimal entry point and point-constrained control to maintain consistent navigation through this point, minimizing tissue contact. Technical performance was evaluated through trajectory-following and point-crossing tests, followed by feasibility experiments in a simulated scenario. Trials were conducted by three cardiologists using a validated phantom model under fluoroscopic guidance, comparing SDS with joint control (JC) and manual control (MC). Results: Average root mean square errors were 2.10 mm for tip position control and 1.86 mm for point-constrained control. SDS outperformed MC with significantly shorter trajectory lengths and lower root mean square jerk. Compared to JC, SDS reduced sheath-induced movements (an indirect measure of force) and increased retraction success rates at the fossa ovalis. Conclusion: The proposed robotic system reduced tissue wall contact compared to JC and provided smoother, more controlled operations than MC, ensuring safer and more effective delivery through confined pathways. Significance: This work contributes to advancing robotic-assisted cardiac sheath delivery, providing a reliable and safer method for navigating challenging anatomical structures. © 2025 IEEE Computer Society.

This paper discusses a novel optimization method to design statically balanced manipulators. Only springs are used to balance the manipulators composed of revolute (R) joints. Since the total potential energy of the system is constant when statically balanced, the sum of squared differences between the two potential energy when giving different random values of joint variables is set as the objective function. Then the optimization tool of MATLAB is used to obtain the spring attachment points. The results show that for a 1-link manipulator mounted on an R joint, in addition to attaching the spring right above the R joint, the attachment point can have offset. It also indicates that an arbitrary spatial manipulator with n link, whose weight cannot be neglected, can be balanced using n springs. Using this method, the static balancing can be readily achieved, with multiple solutions. Copyright © 2020 ASME.

The purpose of this study is to examine potential machine learning techniques that could have been applied to predict spinal abnormalities. Univariate extraction of features as just a filtration system for selecting the features and principal component analysis (PCA) as just a tool for features extracted are one of the data preprocessing stages. A variety of machine learning methodologies, SVM classifier (SVM), regression models (LR), and bagging classification techniques, are now being examined as well for the diagnosis of spinal abnormalities. The Support Vector Machine, Logistic Regression, bagging Svm Classifier, bagging Logistic Multiple regressions are used on a data of 300 sample images inside the Kaggle source. The effectiveness of identification of aberrant and healthy spinal patients is assessed using several parameters, such traas is n and test correct True Negatives, recall, and miss rates. The categorization model was analyzed to use the receiver- operating characteristic (ROC) and highly accurate curves, and the kernel parameters. The obtained training prediction accuracy for Svm Classifier, Logistic Regression, bagged Svm Classifier, and bag Logistic Regression are 86 %, 86 %, and 85 percent, correspondingly, if % of input could be characterized for training. For testing data, the prediction accuracy for Svm Classifier, Logistic Regression, bagging Support Vector Machine, and bagging Regression Analysis all are 87%.

The METERON project (Multipurpose End-To-End robotics Operations Network) was implemented by the European Space Agency as an initiative to prepare Europe for future human-robotic exploration scenarios that in particular, focused on examination of the human-robotic partnership, and how this partnership could be optimized through an evaluation of the tools and methodologies utilized in the experiments in the domains of operations, communications and robotics (specifically with respect to control strategies). Implemented through series of experiments of gradually increasing complexity, the project was originally conceived to culminate in the control of a rover-robot located at a terrestrial analogue site. Being operated by a geology-trained astronaut from the International Space Station (ISS), such a test would enable a reasonably high-fidelity examination of how crew on an orbiting vehicle around the Moon or Mars could remotely perform exploration tasks in an unstructured environment in close collaboration with operations teams at various centres on Earth. In early 2019, Lanzarote was selected as the terrestrial analogue site due to its lunar-like terrain coupled with the fact that the Tinguaton area had been used by the European Astronaut Centre's PANGAEA astronaut training course in 2017. Alignment of ISS planning with the unpredictable constraints of an outdoor planning drove the team to decide to split METERON Analog-1 into two segments: control of the rover/robot from the ISS as an excellent analogue of the Lunar Gateway, together with a more realistic ground analogue campaign - Mount Etna in this instance - where the Gateway analogue was simplified to a room in a nearby hotel. The Mount Etna test was performed in cooperation with the DLR ARCHES campaign in June-July 2022 through implementation of a joint 'space demo mission' - described in detail in a companion paper in this Congress - addressing geology and radio astronomy [1].

AIP Conference Proceedings 2022年第1期2386卷

作者： Hussban Abood Saber Ali Jafer Mahdi Manal Hussein Nawir Shah Fahad Muhammad Shahzad Nazir Arman Goudarzi 1Department of Electrical and Electronics Engineering University of Kerbala Karbala Iraq 2Department of Electrical Engineering Zhejiang University P.R.

High-frequency electrosurgical generator (ESG) is an efficient medical device that is used in surgery for cutting and coagulation of tissues. ESG produces high-frequency alternating current in order to reduce the stimulation of muscles and nerves. The main objectives of the proposed study are: (i) Design and analysis of ESG with cost-effective power converters; and (ii) Investigation of the effect of high switching frequency on the design and performance of the power-electronic converters. The proposed ESG consists of a buck converter (considering its parasitic elements) and H-bridge inverter connected with a high-frequency linear transformer. The proposed ESG is tested on various bio impedances to find the optimal frequency that achieves satisfactory performance. The numerical analysis and simulation results of the proposed study have concluded that, increasing the switching frequency in the DC side decreases the efficiency of the DC-DC buck converter. Also, in the AC side, the rise time of the output voltage is decreased. It is also found that increasing the switching frequency in the AC side will consequently decrease the time period of the surgical operation. These findings can successfully aid in minimizing the blood loss.
