The operating principle of the device is based on the deflection of a laminar gas stream due to the Coriolis effect; it is then a gyrometer with no solid proof mass. A warm gas jet is generated by a micropump through a microfluidic channel opening into a cavity. Two temperature detectors are placed symmetrically with respect to the axis of the flow and their differential temperature is measured. The latter is a function of the rotational velocity applied to the system. The influence of flow velocity on the sensitivity was studied. In addition, the simulation allowed us to determine an optimum detectors geometry in order to find the best sensitivity. The numerical study also made it possible to determine an optimum detectors position (1000 μm) in order to define a compromise between high sensitivity and large measuring range.","PeriodicalId":354534,"journal":{"name":"2017 Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS (DTIP)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125241689","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}

Stress values obtained are lower than the elastic stress on the copper layer which corroborate SEM analysis where copper films present absence of cracks after an annealing at 200°C during one hour. On the other hand, an experimental critical stress characterization has been performed.

Based on U-shape structure, such actuator has been employed in several MEMS applications where fine and repeatable positioning is required. The studied electrothermal actuator here is microfabricated on a doped SOI substrate and its dynamic response, during heating and cooling cycles, is recorded using precise and high-speed camera. To explain its dynamic behavior, FEM simulations, using Comsol multiphysics software facility, are carried out. The result of this numerical analysis shows a strong relationship between the temperature distribution and the displacement provided by the actuator. Finally, the influence of the dynamic behavior on the control of the actuator is discussed using experimental characterizations of its displacements under several voltage pulses with different frequencies.","PeriodicalId":354534,"journal":{"name":"2017 Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS (DTIP)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121417055","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 chambers are filled with magnetic nanopar-ticles and continuous flow is applied in them. Our goal was to find a good and simple geometry to ensure that the flow-through times, therefore the reaction times at most of the laminar flow lines are similar in the chamber. The homogeneity of the velocity field is also desired. For the investigations we performed CFD simulations. A simple method for the reaction time calculation is presented. New geometries are simulated and compared with the original chamber shape used in our previous experiments. The results are promising, in the new geometries the reaction time distribution in the middle of the chamber as well as the velocity field is more homogeneous than in the original case. The simulations were done with the help of the open source CFD software OpenFOAM. Based on the simulation results new microfluidic structures were designed for the further experiments with the magnetic nanoparticles.","PeriodicalId":354534,"journal":{"name":"2017 Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS (DTIP)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125121758","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 first part is the calculation of each layer's microlens array focus on the same surfaces, Then the light path can be simulated by the optic simulation software, ZEMAX. The second part is the bionic microlens array compound eye fabrication. The photoresist column array fabricated by lithography and followed by the thermal reflow can form the microlens array. Elastic PDMS was used as a plastic replicate after sputtering. Then the 3D printer was used to print the PDMS model which was concave curved surface as a hemispherical lens mold and attached the replicated microlens array on the openings. The microlens array can be formed the curvature compound eye microlens array because of the negative pressure resulted in the hemisphere.

We tested the method with a simple 2D example containing 125 internal nodes. For testing the proposed new calculation method multiple combinations of Dirichlet and Neumann type boundary conditions were applied. Also, different types of thermal loads such as prescribed unit-step change in dissipation or temperature were assumed (for time domain transient analysis). The test case was also studied with the assumption of sinusoidal dissipation. Results obtained by the proposed new calculation method and results obtained by conventional simulations differ less than the uncertainty of the traditional solution method. The good agreement enables us to use the balanced truncation method to reduce the order of the transfer functions with low computational cost.","PeriodicalId":354534,"journal":{"name":"2017 Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS (DTIP)","volume":"441 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120881619","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}

In our concept the microscale channels are integrated into the back surface metallization, the microscale channels are formed by electroplating copper around a photoresist channel pattern. This approach has the advantage that it has no restrictions regarding the solar cell material and technology. In this work we give a description on the process technology, perform mechanical simulations for the feasibility of our approach, optimize the channel geometry for a 20 × 20 mm concentrator solar cell and estimate the cooling performance of the microscale channel structure at different operating conditions. We found, that the proposed cooling solution would have a calculated thermal resistance of 0.26 K/W at pressure drop of 100 kPa. This would result in a temperature raise of less than 8 K in case of a concentration level of 100 suns and a solar cell efficiency of 25 %.","PeriodicalId":354534,"journal":{"name":"2017 Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS (DTIP)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131232972","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}
