In this dissertation, cooling stimulation was implemented and demonstrated on cerebral cortex of rats. Electrodes with needle structure was designed and fabricated by using MEMS technology to minimize the size of device. A TE cooler was used to create cooling source and it can be control via electrical current. A cooler component was integrated with an electrode and a TE cooler, in addition, a thermal sensor was also combined with it to detect temperature variation, which was affected by cooling cerebral cortex. The cooler components were implanted on surface of cerebral with deep brain stimulation and the thermal sensors were penetrated into cortex to measure temperature variation which can verify the functions of cooler components. In our experimental results, electrodes with needle structure can improve efficiency of epilepsy suppression due to the particular structure. Duration, frequency and average single time of epileptic waveforms were used to identify to performance of suppression.","PeriodicalId":308928,"journal":{"name":"The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"34 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114136783","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}

Since the CYTOP layer, whose refractive index is as same as that of water, is sandwiched between PDMS and glass substrate, leakage of incident light is avoided. PDMS layer upon the CYTOP enables high aspect ratio structures and easy integration of microfluidic components. Since direct bonding of CYTOP and PDMS is difficult to achieve, a chemical bonding method using aminosilane coupling reagent and 3-Glycoidoxypropyltriethoxysilane was applied. The bond strength was about 0.74 MPa. 24 × 50 microwell array was fabricated and their optical properties was evaluated. Measured TIRE microscopy results shows no interfere with incident light under the conventionally used conditions.","PeriodicalId":308928,"journal":{"name":"The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115280720","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}

Mono-layer, bi-layer and few-layer graphene devices with different dimensions were designed and fabricated. Temperature sensing behavior of graphene has been studied in a small temperature range from room temperature (RT) to 80°C because this range is important in electronic instrumentations and integrated circuit design. Thermal inertia of the graphenes was studied at a temperature of 80°C and the sensing behavior was characterized by measuring the time response of the normalized resistances. Our preliminary results demonstrated a higher negative temperature coefficient of the bilayer graphene those of mono-layer and few-layer graphenes. In addition, engineered graphene resistance based on its dimension has been investigated. This technique provides a strong candidate for temperature sensing in the micro and nano industrial applications with high reliability, high sensitivity and low cost.","PeriodicalId":308928,"journal":{"name":"The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116690945","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}

Currently, due to the lack of control techniques that automatically control cell transfer while locating the cell within optical trap consistently, cells must be manipulated carefully to avoid escape from optical trap, which significantly decreases the efficiency of manipulation task. As a result, the development of a control method for rapid and accurate positioning of cells is becoming a very challenging issue. In this paper, we addressed this challenging problem by developing a unique vision feedback control method that controls both cell positioning and cell trapping simultaneously. We first establish a new geometric model to confine the cell within a local region specified near the optical trap and form a Cell-Tweezers Coalition (C-T Coalition) during manipulation. Then, a potential field function based controller is proposed to drive C-T Coalition to the desired position. Experiments of yeast cell manipulation are performed to demonstrate the effectiveness of the proposed approach.","PeriodicalId":308928,"journal":{"name":"The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121735638","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}

But much channel will result higher pressure difference issue in the micro multi-channel heat sink. In this paper, a ladder shape channel (link between the parallel channel) is proposed to correct the problem of high pressure difference. The design of the link decreases the pressure difference for reducing the pump work of the micro multichannel heat sink. The purpose of this paper is to maximize the efficiency of the micro multi-channel ladder shape heat sink by using optimization design. An optimization method based on the genetic algorithm and COMSOL 3-D conjugated thermal-fluid model is applied to establish the optimal geometry parameters of the link. The results show that this optimized heat sink design can improve the efficiency more than 43%.
