While these types of manipulators can be used in complex environments, often their weight becomes impractically heavy due to the large number of actuators required for a large number of degrees of freedom. Biomimetic manipulators have received attention as a possible solution for the above problem, by imitating biological systems in which a large number of joints are driven by cooperation of muscles. However, these approaches often don't achieve the desired weight reduction as a whole system, due to the need for an air compressor. As such, the purpose of our research is a hyper-redundant manipulator designed with the intention of weight saving over the whole system.","PeriodicalId":181514,"journal":{"name":"2014 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132329278","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}

The objective of this research is to study on the decisive factor of human being in differentiating the thickness between two thin foils; which is the stainless steel and copper. In this study, the finite element (FE) simulation of the fingertip's 3D elastic model has been performed by the aid of CATIA V5. From calculated results, we examined the displacement rate of the foil. As a result, the displacement rate for copper (which was monitored at the foil surface) is always higher compared to stainless steel. By comparing with previous psychophysics result, the simulation also proves similar traits; where human subjects discriminate thickness of foil according to material hardness when t <; 100 μm, thickness is undetermined when 100 <; t <; 350 μm and evaluation is done via another system when t > 350 μm.","PeriodicalId":181514,"journal":{"name":"2014 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132359334","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}

During formation of the morphologies of these structures, apico-basal polarity is regulated by secretion of laminins and integrins. In this study, we observed epithelial cells with mushroom-like 3-D morphologies; many of these cells had tail structures, where endogenous laminin-α3, laminin-β1, and integrin-β1 were found to be accumulated. Interestingly, time-lapse observation of the cells showed rotational movement around the tail. We also observed the process of change from the single-cell morphology to the mushroom-like morphology. Additionally, we observed that single cells showed an elongated protrusion as a predecessor of the tail structure. In addition to laminin-α3, laminin-β1, and integrin-β1, laminin-β3 was also found to be localized in the protrusion. These results indicate that the apico-basal polarization and regulation of laminin secretion are crucial for the formation of the mushroom-like structure and for the rotational movement of Madin-Darby canine kidney (MDCK) cells cultured on Matrigel.","PeriodicalId":181514,"journal":{"name":"2014 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125101576","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 recently developed an nano needle array cell membrane perforator which is containing photosensitizer for mass cell processing and a robotic processing system. However, There were problems that the perforating processing efficiency for floating cells was low and that the sequential processing could not be performed in the method. In order to apply the perforating method to a cell therapy, we should devise the system components which can perform sequential perforation processing. In this report, we developed core components of the process for cell suspensions. The components are membrane filter and its supporting block, to support the cells during the perforation process and to pass through the medium. We evaluated the system with a fluorochrome introduction to the cells. With the system, we could inject membrane impermeable fluorescent dye AlexaFluor594 to the floating rat PC12 cells. This reveals that our sequential cell processing concept is adequate. By combining some flow control system for feeding the cell suspension, the system will be developed as an automatic bed-side cell processing system for various cell therapies.","PeriodicalId":181514,"journal":{"name":"2014 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127028515","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}
