Purpose: With the increasing incidence of cardiac arrests in non-critical areas, it is crucial to provide comprehensive training to healthcare professionals. Simulation-based training using manikins offers a morally sound alternative to traditional methods and allows students to apply clinical skills in realistic scenarios. Usability evaluation, including assessment of efficiency, effectiveness, and user satisfaction, is essential for ensuring the effectiveness of the training. This research focuses on evaluating the usability of the simulation manikin for teaching cardiopulmonary resuscitation to medical students. Methods: Twenty-one volunteers participated in the experiments: 18 students and three teaching doctors (one instructor professor and two evaluator professors). The instructor professor was instructed to follow the same procedure used in the classroom setting. The evaluating professors were provided with appropriately labeled data collection instruments to evaluate the usability of manikins. The student performed the tasks as instructed, and after completion, they were directed to the debriefing room, where they filled out the feedback form. Results: The experimental data and the statistical analyses showed that regarding effectiveness, the study findings indicated that participants encountered difficulties in certain tasks, as evidenced by the need for significant intervention from the instructor professor. In relation to efficiency, the results demonstrated a clear correlation between the successful execution of tasks and the duration of instruction provided by the instructor, thereby indicating the presence of a usability problem associated with the simulation manikin. And users are not entirely satisfied with the manikin, considering the room for improvement indicated by the SUS score. Conclusion: The experiment and the results reported in this paper contribute to addressing the existing gap in the literature concerning the usability of high-fidelity s

Assessment of impaired insulin secretion and insulin resistance are critical to determining the type of diabetes and planning optimal management and preventive strategies in clinical practice. To measure insulin resistance, a minimally invasive needle with measurement and administration flow channels for local glucose tolerance tests was fabricated. The administration flow channel has a hole on the tip end of the flow channel. The microperfusion flow channel starts from the root side of the needle, turns around at the needle-tip end, and returns back to the root side of the needle. It has a perforated membrane on the surface of the area placed in the skin when inserted. Glucose is administrated through the flow channel, and glucose concentration of the skin is measured by microperfusion before and after administration. When the perfusate is perfused into the microperfusion flow channel, since the glucose concentration of the skin is higher than the perfusate, glucose contained in the skin’s interstitial fluid moves into the flow channel through the perforated membrane by concentration diffusion, and the glucose can be collected. The needle’s administration and glucose-collecting functions were evaluated in the skin of mice. © 2025 The Institute of Electrical Engineers of Japan.

A powerless liquid transfer system for wearable skin microperfusion was fabricated. In our previous work, minimally invasive microperfusion needle which collects biological substances from subepidermal tissue had been developed. The liquid transfer system for skin microperfusion requires low flow rate, constant flow rate, low power driven, disposability, and small size. The fabricated powerless liquid transfer system is driven by a combination of a passive constant flow valve with a PDMS membrane laminated between PMMA plates, and a vacuum chamber. The fabricated liquid transfer system has a flow rate of less than 5 µl/min (fluctuations were less than 1 µl/min) for more than 120 minutes. In addition, this liquid transfer system was possible to meet the required specifications even when a fluid resistor was inserted to simulate the same level of pressure drop as the microperfusion needle and sensor. © 2025 The Institute of Electrical Engineers of Japan.

Thin-walled tubes have been extensively used as energy absorbers in many engineering structures that are under dynamic or quasi-static loads. In this article, the effect of corrugation and its geometry on the collapse characteristics of aluminum concertina tubes under quasi-static axial load is investigated both experimentally and numerically. The numerical simulations were performed with the use of LS-Dyna commercial software. Then, several chosen samples were tested experimentally to verify the results of the simulation. Forty different samples with four different corrugation geometries including singly isosceles triangular corrugation, continual isosceles triangular corrugation, continual scalene triangular corrugation, and continual semi-circular corrugation, and each with 10 different size dimensions were simulated. Among all of these simulations, six of them, each with two replicates were subjected to experimental tests. Experimental examples are aluminum cylindrical thin-walled tubes with the same thickness, height, and diameter that corrugations with different geometries are applied to them by the use of the cold rolling method. Finally, to describe the findings in more theoretical terms, a comparison between our obtained results and earlier theoretical investigations is made. The results show a significant influence of corrugations application on the improvement of the collapse characteristics of the cylindrical tubes so that the collapse style of intact tubes can be controlled by applying corrugations. The results show that by increasing the amplitude and number of corrugations, the absorbed energy, and the initial maximum force decrease. It is also found that among the different corrugation geometries, the corrugations with singly isosceles triangular geometry have the highest energy absorption as well as the lowest initial maximum force. © 2023 Taylor & Francis Group, LLC.

Work-related musculoskeletal disorders (WMSDs) are often caused by repetitive lifting, making them a significant concern in occupational health. Although wearable assist devices have become the norm for mitigating the risk of back pain, most spinal assist devices still possess a partially rigid structure that impacts the user's comfort and flexibility. This paper addresses this issue by presenting a smart textile-actuated spine assistance robotic exosuit (SARE), which can conform to the back seamlessly without impeding the user's movement and is incredibly lightweight. The SARE can assist the human erector spinae to complete any action with virtually infinite degrees of freedom. To detect the strain on the spine and to control the smart textile automatically, a soft knitting sensor which utilizes fluid pressure as sensing element is used. The new device is validated experimentally with human subjects where it reduces peak electromyography (EMG) signals of lumbar erector spinae by 32%± 15% in loaded and 22%± 8.2% in unloaded conditions. Moreover, the integrated EMG decreased by 24.2%± 13.6% under loaded condition and 22.6%± 9% under unloaded condition. In summary, the artificial muscle wearable device represents an anatomical solution to reduce the risk of muscle strain, metabolic energy cost and back pain associated with repetitive lifting tasks. © 2024 IEEE.

Titanium dioxide with suitable band edges is one of promising photocatalysts for water splitting. Nanotubes with one-dimensional structure can induce efficient charge transfers and hollow centers can provide large surface area for surface reactions. Modifying Ti foils for anodization can enhance light utilization of TiO2 nanotube photoelectrodes. In this work, it is firstly to fabricate TiO2 nanotube photoelectrodes on acid-etched Ti foils by anodization (MNT) for photoelectrochemical catalyzing water splitting. Different acid-etching durations are applied on Ti foils to induce various rugged surfaces. The resulting photoelectrodes present largely enhanced light utilization than that fabricated by the pristine Ti foil. The anodization duration is also optimized to find suitable lengths of MNT. The smallest overpotential of 524.7 mV at 10 mA/cm2 and Tafel slope of 167 mV/dec are obtained for the optimal MNT photoelectrode. The TiO2 nanotubes grown on the pristine Ti foil shows the overpotential of 679.3 mV at 10 mA/cm2 and Tafel slope of 285 mV/dec. This result opens a blueprint for raising the photocatalytic ability by simply modifying the surface property of the conductive substrate. Other modifications may be applicable to enhance the roughness of Ti foils for growing more efficient MNT array as photocatalysis of water splitting. © 2023 Hydrogen Energy Publications LLC

Nowadays, industrial processes are creating increasing demands for optimized and efficient sensing systems and require high reliability and a short time interval for information delivery. This paper presents an embedded sensor system that uses the ESP-NOW protocol with a Mesh and Ad Hoc network, in order to provide an auto mesh configuration upon failure at some point in the network. This system was implemented to monitor the variables of an induction motor, after which, before sending the data to the cloud, local processing is performed to reduce the volume of data. Finally, a computer simulation of the WROOM-32 module is performed for a thermal analysis during its operation, where the heating points of the plate are identified and analyzed, in order to validate that the system, even processing a large amount of data, maintains a high reliability during its operation. ©2023 IEEE.

Purpose: The primary objective of this study is to present, analyze, and quantitatively characterize the electrical signals obtained from neuronal cultures coupled to micro-electrode arrays (MEAs). Special attention is given to the temporal evolution of electrical activity across distinct geometric regions of the MEA devices. Methods: The proposed methodology involves signal acquisition, classical analysis based on spike and burst detection, and, critically, the characterization of the probability density structure of the signals. This is achieved through the quantification of Gaussianity—expressed as the percentage of segments non-Gaussian (PSNG)—and stationarity— expressed as the percentage of segments non-stationary (PSNE). Results: Initial analyses showed that first-order power spectral density quantifiers lacked the statistical robustness required to effectively describe the complex components of MEA signals. In contrast, PSNG and PSNE demonstrated strong potential in capturing the different stages of neuronal culture development. Cluster analysis further supported the discriminative capacity of these quantifiers. Conclusion: The phase corresponding to decreased neuronal activity and onset of cell death—a biologically critical stage—exhibited the strongest correlation among the studied variables. These results suggest a discernible biological organization and highlight the relevance of PSNG and PSNE as promising tools for assessing neuronal culture dynamics. © The Author(s), under exclusive licence to The Brazilian Society of biomedical engineering 2025.

The precise detection of cephalometric landmarks on two-dimensional (2D) radiographs or three-dimensional (3D) computed tomography (CT) images is a fundamental step in various medical fields, especially in research on orthodontics and maxillofacial surgery. Deep learning-based detectors have demonstrated remarkable accuracy in 2D cephalometric analysis, whereas conventional single-view approaches are limited by their reliance on information from a single perspective. This study proposes GeoRefineNet, a novel multistage framework that leverages information from multiple CT scans acquired at various angles. By incorporating geometric knowledge through a 3D heatmap reconstruction process, GeoRefineNet improves robustness, accuracy, and adaptability to various cephalometric configurations. The proposed framework predicts 3D landmark positions on CT images, effectively addressing challenges associated with high-dimensional input data and limited training examples. GeoRefineNet surpasses the existing state-of-the-art models in the 2D and 3D domains, as demonstrated by its superior performance on numerical and clinical datasets. These findings indicate that GeoRefineNet offers a promising avenue for improving the accuracy and reliability of cephalometric landmark detection fostering further advances in clinical diagnosis and treatment planning.
