In this research, we developed a nanomanipulation method of nanometer scale objects using a high-speed tapping mode AFM. As for manipulation nanoobjects, one-dimensional materials such as carbon nanotubes were used. Tapping mode was employed to image the objects without dragging them on the surface. In the manipulation mode, the feedback point of the amplitude of the cantilever oscillation was much reduced, which allowed us to push and move the objects on the surface as if it was operated like a contact mode. By adding circular or linear oscillations in the horizontal plane to the cantilever tip, the object was effectively moved or cut on the substrate.","PeriodicalId":264161,"journal":{"name":"2019 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"94 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121012058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetostrictive force sensors are the most promising, lightweight, and reliable sensing technologies; however, an in-depth understanding of the sensing mechanism is still lacking. In this study, we focus on magnetic Barkhausen noise (MBN), which is generated by the inverse magnetostriction effect upon impact loading. Further, the stress-induced MBN characteristics of Fe-Co alloy/epoxy composites were investigated using a cyclic compression test. By measuring and analyzing MBN signals in magnetostrictive/epoxy resin composites, it was revealed that the root mean square value of MBN increased linearly with the increase in the stress rate. Additionally, we observed that the MBN outbreaks were affected by the magnetostriction constant. The proposed MBN force sensor system is expected to achieve high sensitivity, wide measurement range, and downsizing.","PeriodicalId":264161,"journal":{"name":"2019 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127100657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used 3D motion analysis equipment and floor reaction force meters to investigate characteristics of normal walking, wide walking, and pole walking. Data of joint moments, coordinate values, and floor reaction forces related to normal walking, wide walking, and pole walking were compared. Through several experiments, we confirmed features of pole walking characteristics compared to those of normal walking and wide walking. This study investigated characteristics of normal walking, wide walking, and pole walking using 3D motion analysis equipment and floor reaction force meters, comparing data of joint moments, coordinate values, and floor reaction forces for normal walking, wide walking, and pole walking. Recently in Japan, a complete medical system and implementation of municipal governments' insurance based on the law for the welfare of elderly people have contributed to reduction of mortality, but those measures have not contributed to improvement of health. Therefore, pole walking increasingly attracts attention not only to support elderly people but also to maintain good health practically and personally. For the walking style defined for this study, two poles are held in the hands when stepping with the right leg. The walker then pokes the ground on the left side of the right foot with the pole held in the left hand. When stepping with the left leg, one pokes the ground with a pole held in the right hand as during climbing or skiing, doing pole walking. For this study, we conducted some experiments to compare the characteristics of normal walking, wide walking, and pole walking. For the experiments, we measured the ankle joint moments, hip joint moments, and knee joint moments. We confirmed through experimentation that the maxima of the joint moments during pole walking are smaller than those during either normal walking or wide walking.","PeriodicalId":264161,"journal":{"name":"2019 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122071032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, experiments so far have explored this phenomenon with visual instructions. To explore head and gaze anticipation without visual influence, we describe a system for instruction and measurement of auditory instructed locomotion. The objective of this work is to describe the system setup and validate its accuracy for scientific investigations in locomotion research. The system is comprised of an auralization server that plays virtual sound sources via wireless headphones. The auralization is fed with head position and orientation angle measured by a Vicon motion tracking system. Communication between the auralization server and the motion tracking host was facilitating the OSC protocol. Auditory instructed locomotion was performed in two visual condition: eyes open and eyes closed for comparison. First, ten sighted participants localized static virtual sound sources at eight positions to confirm the accuracy of the provided virtual sound cues. Afterwards, they listened and actively followed virtual sound sources that were moving along three trajectories: an eight shape, a circle in clockwise direction and a circle in anticlockwise direction. The virtual sound sources could be localized with an accuracy of 0.16 meters in the eyes open condition and 0.12 meters in the eyes closed condition. Participants also were able to follow the moving sound sources.","PeriodicalId":264161,"journal":{"name":"2019 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130346469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently years, many more detailed musculoskeletal models have been developed. However, most of them are constructed by straight muscles (Via-Point muscle), and the number of lower extremity models that reproduce actual muscle path is few. In this study, we developed the lower extremity musculoskeletal model which reproduced the actual muscle path and validated the accuracy by using motion analysis data. First, we constructed to connect the origin and insertion point of lower extremity muscles determined from the anatomical book on a bone model constructed from lower extremity musculoskeletal model data set provided by Anybody Modeling System Via-Point muscle. After that, we constructed a Wrapping muscle that reproduces the curvilinear shape of the muscle by putting the Via-Point muscle along multiple ellipsoids. Secondly, we conducted the inverse dynamics analysis using motion analysis data to validate the accuracy of the developed model. For the verification, we used the walking data of Total Hip Arthroplasty patient and the hip contact force (HCF) provided by the OrthoLoad. Reflecting these data in the developed model, we conducted the inverse dynamics analysis to calculate the anterior-posterior, medial-lateral, and proximal-distal components of the HCF. We calculated the mean squared error (RMSE) of the predicted value (HCFpredicted) and the actual value (HCFMeasured) for the HCF calculated by resulting the three axial direction components. As well as, we also calculated RMSE of the default model to compare the developed model. As a result, the RMSE of HCFMeasuredand HCFPredicted was 0.208 * BW for HCFMeasured. In addition, the RMSE of HCF Predicted calculated with the default model provided by AMS is 0.359 * BW, which showed to reduce the error by 40%. Based on the results of this study, it was possible to develop a model with higher accuracy than in the past by reconsidering the origin and insertion of the muscle path into a shape closer to that of the actual body.","PeriodicalId":264161,"journal":{"name":"2019 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129570894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aim to solve this problem using a swing motion that is robust over a large range of spin patterns without accurate recognition of the spin. Specifically, we examine the relation between the swing speed and direction of return. When the racket speed is 7 m/s, the difference in the return direction is only 20 % of that when the racket is not swung for the ball spinning in the range from -20 to 20 rev/s. In addition, we investigate the increase in swing speed of the racket due to flexibility of the swinging arm. We find that a flexible arm swings more rapidly than a rigid arm throughout the range of motion when exploiting the joint angle limit.","PeriodicalId":264161,"journal":{"name":"2019 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127358113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
