Both driving and sensing modes of the gyroscope are dominated by slide film air damping, then it can work even at atmosphere. Novel driving comb capacitors are used to electrically decouple the mechanical coupling from sensing mode to driving mode. The process for this gyroscope is also compatible with z-axis gyroscope, which makes it potentially to realize low coast monolithic MIMU (miniature inertial measurement unit) without vacuum packaging. The TFG was fabricated and tested at atmosphere. The sensitivity is 17.8mV/°/s while the nonlinearity is 0.6%.

Currently used Couette rheometer drives the blood flow at a certain shear rate and measures the viscosity from the resistance toque towards the rotational shaft. Although effective, conventional rheometer is limited due to the complex configuration and the relatively large sample volume. More important, the rotating components hinder the miniaturization for point-of-care and unattended diagnosis. To address this, a microchip is reported for measuring the blood viscosity from the electrical impedances of the blood flowing inside a microchannel. This microdevice is advantageous over rotational viscometers in less sample consumption, rapid response and simple configuration. Considering the vital role of blood viscosity in cardiovascular disorders, this microchip provides a promising start point for on-chip hematological diagnosis.","PeriodicalId":187850,"journal":{"name":"2009 IEEE 22nd International Conference on Micro Electro Mechanical Systems","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134576228","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 performance of the new concept has been analyzed theoretically and was experimentally verified by contact resistance and life-time characterization of fabricated MEMS switches with conventional Au-Au and with the novel Au/Ru-Ru/Au contact metallization scheme. The switches are based on a low-stress SiN/SiO2 diaphragm which is polymer transfer-bonded and equipped with corrugations for reducing the stiffness and for lowering the stress. The reduced stiffness allows for early encapsulation by clamping the membrane all around its circumference, by maintaining medium actuation voltages.","PeriodicalId":187850,"journal":{"name":"2009 IEEE 22nd International Conference on Micro Electro Mechanical Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133687142","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 dynamic patterning of nanoparticles was achieved by a standing surface acoustic wave (SSAW), from which the acoustic force generated and force the particles to the pressure nodes. The SSAW were formed through two parallel interdigital transducers (IDTs) on a LiNbO3 substrate, on which the gold nanodisk arrays were fabricated through a nanosphere lithography. A PDMS microchannel was aligned with the IDTs and bonded with the substrate to cover the nanodisk arrays. A solution of fluorescent polystyrene beads (diameter: 320 nm) was injected into the channel through a pressure driven flow.

The tunable system is based on a pneumatically actuated micro-lens for the axial movement of the focus position concomitantly with the depth scan of the OCT, whereas an electrostatically actuated micro-mirror is integrated to obtain the 2D lateral scan of the beam.

The present stretchable substrate is able to provide the areal strain of 5.21%~12.3% for the input pressure of 34.5kPa~103kPa.
