    Development of a Force Sensor for Biomechanical Simulations of a Cycling Activity
    (IEEE, 2022) Karacaoğlu, Bilal; Şahin, Ahmet Mert; Çıklaçandır, Samet; Yılmaz, Mehmet; Mihçin, Şenay
    Knowing the forces applied to the pedals during a cycling activity is of great importance in the field of biomechanics when calculating the loads acting on the joints. A load cell-based force sensor was designed for this purpose since the force plate fixed to the floor in gait laboratories cannot be used to measure the reaction forces on the bicycle pedal due to physical constraints. To investigate the accuracy and precision of the force plate, a two-stage experiment, static and dynamic force measurement tests were designed. First, the first static measurements were carried out with standard loads of 1000 g, 1200 g, 1500 g. To understand the behavior of the sensors under dynamic loading, dynamic measurements were conducted while the designed force sensor is attached to the bike pedal while using a commercially available power meter simultaneously to cross-validate the measured forces. Standard loads of 1000 g, 1200 g, and 1500 g were measured as 1020 ± 2 g, 1196 ± 2 g, and 1512 ± 1 g respectively. To assess the agreement between measurements Bland-Altman plot analysis was carried out. The Bland-Altman plots showed that the force platform is appropriate for both measuring static loads and dynamic loads. The collected data via this custom-made, affordable force sensor was successfully fed into the biomechanical modeling software to calculate the joint reaction forces.

    Design and Manufacturing of a Hip Joint Motion Simulator With a Novel Modular Design Approach
    (Springer, 2024) Torabnia, S.; Mihçin, D.Ş.; Lazoglu, I.
    The study is aimed to develop a hip joint wear simulator using a modular design approach to help experimentally monitor and control critical wear parameters to validate in-silico wear models. The proper control and application of wear parameters such as the range of motion, and the applied force values while estimating the lost material due to wear are essential for thorough analysis of wear phenomena for artificial joints. The simulator's dynamics were first modeled, then dynamic loading data was used to calculate the forces, which were further used for topology optimization to reduce the forces acting on each joint. The reduction of the link weights, connected to the actuators, intends to improve the quality of motion transferred to the femoral head. The modular design approach enables topology-optimized geometry, associated gravitational and dynamic forces, resulting in a cost-effective, energy-efficient product. Moreover, this design allows integration of the subject specific data by allowing different boundary conditions following the requirements of industry 5.0. Overall, the in-vitro motion stimulations of the hip-joint prosthesis and the modular design approach used in the study might help improve the accuracy and the effectiveness of wear simulations, which could lead into the development of better and longer-lasting joint prostheses for all. The subject-specific and society-based daily life data implemented as boundary conditions enable inclusion of the personalized effects. Next, with the results of the simulator, CEN Workshop Agreement (CWA) application is intended to cover the personalized effects for previously excluded populations, providing solution to inclusive design for all. © 2023, The Author(s), under exclusive licence to Springer-Verlag France SAS, part of Springer Nature.

    Üst Ekstremite Hareket Kabiliyeti Değerlendirmesi için Yeni Bir Sistem Tasarımı
    (IEEE, 2020) Çizmecioğulları, Serkan; Mihçin, Şenay; Akan, Aydın; Koçak, Mertcan; Tosun, Aliye
    Üst ekstremite fonksiyon değerlendirilmesinde kullanılan yöntemlerden birisi de Eklem Hareket Açıklığı (EHA) ölçümleridir. Günümüzde bu ölçümler klinisyenin gözlemsel değerlendirmesine ve/veya gonyometrik ölçümlere dayanmaktadır. Bu ölçümlerde tekrarlanabilirlik ve güvenilirlik açısından problemler mevcuttur. Bu çalışmada üst ektremitede EHA ölçümlerinin sayısal değerlendirilmesine bağlı olarak objektif çıkarımlar yapılmasını sağlayabilecek tek kameralı bir sistem önerilmiştir. Bireylerin omuz ve dirsek fleksiyonu hareketleri kaydedilmiştir. Eş zamanlı olarak “Altın Standart” olarak OptiTrack sistemi ile de yapılan hareketler kayıt altına alınmıştır ve analiz edilmiştir. Çalışmaya 9 erkek ve 9 kadın birey katılmıştır. Hareketlerin kaydedilmesi için Kinect kamera kullanılmıştır. Kinect kamera OptiTrack sistemi ile karşılaştırılmıştır. Omuz ve dirsek fleksiyonu açıları her iki sistem ile hesaplanmıştır. Hesaplanan açılar kullanılarak her iki sistemin uyumu istatiksel olarak incelenmiştir. Bland- Altman yöntemi kullanılarak yapılan analizlerde hem erkek hem de kadın bireylerde omuz fleksiyonu ve dirsek fleksiyonu hareketleri açısından %95 güven aralığında her iki kameranın birbiriyle uyumlu olduğu tespit edilmiştir. Bu çalışma önerilen sistemin klinik tanı için güvenirliğine dair delil teşkil etmektedir.

    Design of Stacker Crane for Mini-Load Automated Storage and Retrieval Systems
    (Izmir Institute of Technology, 2022) Bekleviç, Mustafa; Mihçin, Şenay
    The objection of the thesis is to design and analyze a 3 degree of freedom stacker crane mechanism for Mini Load Automated Storage and Retrieval Systems. Automated Storage and Retrieval System (AS/RS) is an automated system in which the product of a company to be stored is placed in or retrieved from specified location on a rack system by means of computer aided mechanism which is nothing but a stacker crane. This study first introduces an inclusive literature review on AS/RSs. Several types of AS/RSs are examined and the differences between them are introduced. Additionally, several types of stacker cranes in the literature are also presented. Moreover, the linear motion systems used in similar mechanism are explained briefly in the chapter. In the design chapter of the thesis, theory of the stacker crane mechanism is introduced. A conceptual design is created and, elements and sub-sections of the desired mechanism are presented with the conceptual design of the mechanism. After the conceptual design, critical design calculations are performed approximately before the detailed design of the mechanism. Afterwards, the detailed design of the mechanism is created and calculations are verified due to detailed design. The detailed design of the mechanism is analyzed using Finite Element Analysis methods in the analysis chapter of the thesis. Analysis of critical components and critical sub-sections of the stacker crane mechanism are analyzed using Computer Aided Engineering program. Revises are made according to the results of the FEA and design is validated at the end. At the prototyping chapter of the thesis, the manufacturing studies of the mechanism are presented. Manufacturing stages are introduced and experiments of the sub-section of the mechanism are done.

    Detailed Investigation of Three-Dimensional Modeling and Printing Technologies From Medical Images To Analyze Femoral Head Fractures Using Finite Element Analysis
    (Elsevier, 2022) Çıklacandır, Samet; Mihçin, Şenay; İşler, Yalçın
    Objectives: One of the fields, where additive manufacturing has numerous applications, is biomedical engineering. 3D printing is preferred over traditional manufacturing methodologies, mostly while developing subject-specific implants and medical devices. This study aims to provide a process flow detailing all the stages starting from the acquisition of radiological images from different imaging modalities; such as computed tomography (CT) and magnetic resonance imaging (MRI) to the printing of the bone morphology and finite element analysis; including the validation process. Materials & Methods: First, the CT scan of a lower abdomen area of a patient was converted into a 3D image using interactive medical imaging control system software. The segmentation process was applied to isolate the femoral head from the soft tissue and the pelvic bone. After the roughness errors and the gaps in the segments were removed using the 3Matic software, the file was converted to stereolithography (STL) file format to transfer to the 3D printer. The printing process was carried out via commercial powder-based Selective Laser Sintering (SLS) printer. The subject-specific femoral head model was formed in 3D. The Finite Element Analysis (FEA) of the femoral head was performed using a commercial FE software package. Results: The results show that experimental analysis and the CT scan-based FEA were compatible both for the stress distributions and the strain values as predicted by the models (R2=0.99). The deviation was calculated as approximately 12% between the experimental results and the Finite Element (FE) results. In addition, it was observed that the SLS technique produced useful results for modeling biomedical tissues with about 24x faster prototyping time. Conclusion: The prescribed process flow could be utilized in clinical settings for the pre-planning of the surgeries (≈428 minutes for femoral head) and also as an educational tool in the biomedical engineering field.

    (01. Izmir Institute of Technology, 2023) Karacaoğlu, Bilal; Mihçin, Şenay
    Evaluation of human movement performance in activities of daily living is an important component in clinical and rehabilitation settings. Motion capture technology is an effective method for objective evaluation of human motion. Here, movement kinematics and kinetic data are obtained from healthy individuals. In this thesis, it is detailed the daily life movements based on stair climbing and cycling. The aim of this study is to examine the effects of human movement on the kinetic and kinematic variables of the hip joint during stair climbing and descending. Data were collected using the Qualisys motion capture system, force plates, ladder and bicycle. By analyzing data from different individuals here, great potential information can be gained for predicting the recovery and progression of movement for patients. In the future, the development of personalized therapy protocols in rehabilitation with individualized progression can be offered. Optimum design parameters for the individual device and exercise device can be obtained, and if the relevant joints are supported with implants, it is possible to obtain the necessary boundary conditions for personalized implant design and to collect the necessary data for implant design. The Results and Discussion Chapter illustrates and tabulates the calculated results. In the Findings and Discussion section of the thesis, the calculated results of the study are included. This section provides a comprehensive analysis of the data collected, highlighting the observed patterns, trends, and variations in hip joint kinematics and kinetics during selected activities. The Discussion section delves into the significance of the findings by comparing the findings with the available literature, identifying similarities and differences, and offering possible explanations for observed variations.

    A Fiber-Driven Finite Element Model for Predicting Residual Limb Soft Tissue Deformation: Applications in Prosthetic Socket Design
    (Springer, 2025) Wang, Ling; Qiu, Ziyan; Tang, Lei; Huang, Fuhao; Wei, Pingping; Mihcin, Senay; Li, Dichen
    PurposeChanges in residual limb volume and shape pose significant challenges in achieving and maintaining an accurate and comfortable fit for prosthetic socket. While numerous techniques for measuring residual limb volume have been proposed, their clinical application remains limited by insufficient resolution and the inability to perform in-socket measurements. To address this issue, this study develops a novel method for predicting residual limb soft tissue deformation to guide prosthetic socket design.MethodsA three-dimensional (3D) finite element (FE) model of the human thigh was developed to simulate the soft tissue deformation during daily activities, driven by muscle contraction to replicate natural biomechanics. The model included hard tissue and muscle components, with the muscle modeled as a structure of evenly distributed, contractile fibers that generate movement. Parameters controlling fiber contraction were iteratively adjusted to best match the calculated tissue deformation and that observed in physical muscle models.ResultsThe optimized FE model significantly improved the accuracy of predicting dynamic soft tissue deformation, with average errors of 0.83% and 1.86% for tissue expansion and contraction regions, respectively. For various gait patterns, the average differences in equivalent volume and cross-sectional area changes were also less than 0.83% and 1.86%, respectively.ConclusionThe model demonstrated consistent prediction accuracy across different gait data. The fiber-driven soft tissue model developed offers a valuable tool for pre-design simulations of prosthetic sockets and orthoses. It is equally applicable to other wearable devices that interface with the skin, providing a robust framework for improving device design and functionality.

    Finite Element Study of Peek Materials Applied in Post-Retained Restorations
    (MDPI, 2022) Yu, Hao; Feng, Zhihong; Wang, Ling; Mihçin, Şenay; Kang, Jianfeng; Bai, Shizhu; Zhao, Yimin
    Background: This study aimed to investigate the biomechanical behaviors of polyether ether ketone (PEEK) and traditional materials (titanium and fiber) when used to restore tooth defects in the form of prefabricated post or customized post via computational modelling. Methods: First, the prototype of natural tooth, and the prototypes of prefabricated post and customized post were established, respectively, whilst the residual root was restored with dentin ferrule using reverse engineering methods. Then, the stress and strain of CFR-PEEK (PEEK reinforced by 30% carbon fiber) and pure PEEK (PEEK without any reprocessing) post were compared with those made in traditional materials using the three-dimensional finite element method. Results: From the stress point of view, compared with metal and fiber posts, CFR-PEEK and pure PEEK prefabricated post both demonstrated reduced post-core interface stress, post stress, post-root cement stress and root cement stress; moreover, CFR-PEEK and pure PEEK customized post demonstrated reduced post stress, post-root cement stress and root cement stress, while the strain of CFR-PEEK post was the closest to that of dentin. Conclusions: Compared with the traditional posts, both the CFR-PEEK and pure PEEK posts could reduce the risk of debonding and vertical root fracture, whether they were used as prefabricated posts or customized posts, but the biomechanical behavior of carbon fiber-reinforced CFR-PEEK restorations was the closest to dentin, no matter if they were used as prefabricated post or customized post. Therefore, the CFR-PEEK post could be more suitable to restore massive tooth defects. Pure PEEK needs filler reinforcement to be used for post-retained restoration.

    (Springer, 2022) Göktaş, Hasan; Subaşı, Eda; Uzkut, Metin; Kara, Mustafa; Biçici, Hamit; Shirazi, Hadi; Mihçin, Şenay
    Total Hip Arthroplasty (THA) is one of the best advancements in healthcare. THA is required when the hip joint causes immobility and pain. The designed hip implants vary in geometry with different geometrical parameters. The geometry plays an important role in the mechanical behavior of the hip implant. In this study, the optimum selection of hip implant under static loading was evaluated using Finite Element Modeling (FEM). Hip implants with three different stem cross-sections including. (a) elliptic, (b) oval, and (c) trapezoidal were designed using a commercial Computer-Aided Design (CAD) software package. The FEM analysis was carried out via ANSYS R2019 to assess the key mechanical parameters of the implants such as stress distribution and deformation. The results were evaluated for the best stress and strain values. The optimum design had equivalent stress (von Misses) of 258,1 MPa, equivalent strain of 0.004, with total deformation of 0.24 mm and frictional stress of 0.362 MPa producing best values for trapezoidal cross-sectioned design. The findings of this study provided an insight into the selection of appropriate hip implant design with certain geometric design parameters to produce optimum results in clinical applications. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
