Deformable coils are thus not compatible with an open- loop class E design. By connecting a transductor in series with the transmitter inductance, it is possible to keep the total class E inductance constant, regardless of the transmitter coil deformation. This is achieved through a control loop that steers the transductor to the appropriate inductance value. For the realized closed-loop circuit, class E regime is maintained for inductance variations of the transmitter coil of up to 27 %. The principal advantage of transductor control compared to earlier reported techniques, is the fixed frequency of operation.","PeriodicalId":23295,"journal":{"name":"TRANSDUCERS 2007 - 2007 International Solid-State Sensors, Actuators and Microsystems Conference","volume":"30 1","pages":"65-68"},"PeriodicalIF":0.0,"publicationDate":"2007-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81101340","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 experimental results are used to calibrate and validate the simulation model to solve the Navier-Stokes equation for fluid flow and Poisson equation to resolve the external electric field. According to the Helmholtz Smoluchowski equation the electroosmotic mobility (muEO) is independent of channel cross-section and applied electric field. Contrary to the above relationship, the results presented in this work indicate that muEO is not constant but changes with channel cross-section as well as the applied electric field. The results of this work will be useful in determining the optimum channel dimensions for a desired electroosmotic velocity at a given applied electric field.","PeriodicalId":23295,"journal":{"name":"TRANSDUCERS 2007 - 2007 International Solid-State Sensors, Actuators and Microsystems Conference","volume":"27 1","pages":"1853-1856"},"PeriodicalIF":0.0,"publicationDate":"2007-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85700712","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 construction of this laser is based on Littman external cavity configuration. The key point is to use two micro-mirrors to select two different wavelengths at their independent diffraction modes, and the emission of both wavelengths will be collected through the 0th order of the grating. Meanwhile, wavelength tuning is achieved by rotating one of the mirrors. As a result, a tunable spectral separation of dual-wave length output is obtained.

We added a new electrostatic latch mechanism to the system to individually control the projection state. We used MEMS technologies to fabricate a 4times4 array electrostatic latch mechanism.

In particular, these are evaluated in the context of the scaling analysis of a Si-micromachined monolithic Knudsen pump. Results from these models are verified using available experimental data and are benchmarked against the simulation results from direct simulation Monte Carlo (DSMC) technique. Characterization of Sharipov's model against the DSMC technique with the help of specially designed test cases predicts that Sharipov's model is potentially the most representative model for DSMC in this context. Finally, Sharipov's model is used to evaluate the sensitivity analysis of structural and performance parameters relevant for thermal transpiration. The analysis shows that for a 200 mum long channel on a well-insulated glass substrate, with a channel height of 100 nm and 10 mum width, provides a mass flow rate of 1.5times10-6 sccm with a DeltaT of 300degC.","PeriodicalId":23295,"journal":{"name":"TRANSDUCERS 2007 - 2007 International Solid-State Sensors, Actuators and Microsystems Conference","volume":"87 1","pages":"2329-2332"},"PeriodicalIF":0.0,"publicationDate":"2007-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76824305","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}
