Glucose is the energy source of living cells. Therefore, measuring the glucose consumption on cells is very important in cell biology. In μTAS research field, an enzyme-fixed micro glucose sensor integrated to microfluidic devices has been proposed for measurement of cell kinetics continuously. There are various methods on how to fix the enzyme to the sensor. In this paper, we examined the performance of the micro glucose sensor fabricated by the different enzyme immobilization methods. We measured the sensitivity and the lifetime of the glucose sensors made by different enzyme immobilization methods. As the result, the sensor sensitivity of the crosslinking method was higher than it of the physisorption method. We conclude that the performance of the micro glucose sensor could be modified by optimization of the enzyme immobilization methods.","PeriodicalId":181514,"journal":{"name":"2014 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"13 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":"121772363","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, the family or the care giver can't easily to go to see him or her because it takes a lot of time and cost to go. And then we decided to develop a remote controllable wheelchair robot with the function of telepresence. On the other hand, the remote control is too risky for a local user of wheelchair robot. A wheelchair robot must be driven safely by a remote user. The purpose of this study is to improve safety of driving of the wheelchair robot by a remote user.

The PV system converts sunlight into electric power. The IV (current-voltage) curve of the solar cell describes its energy conversion capability at the existing conditions of light level. The PV (power-voltage) curve which determines the maximum output power is computed from the IV curve. It is necessary to operate the solar cell at the voltage which provides the maximum power. The maximum power point tracking (MPPT) control using hill-climbing method is widely used. However, the output power from the PV system is reduced if weather condition changes and the area of the receiving portion of the PV panel decreases. In these cases, IV characteristics of the PV panel also changes. There is a possibility that the maximum power point cannot be captured by the conventional MPPT control in case that the maximum power would be two or more. We propose a method for the estimation of the DC voltage at the maximum power point by using the equivalent circuit of the solar cell.","PeriodicalId":181514,"journal":{"name":"2014 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"51 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":"127573942","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}
