The only available measurement method is off-axis LDV, which still shows a serious measurement error depending on the device pattern of the target surface. The on-axis FLDV (Fiber-optic LDV) with a 45°-angled optical fiber is proposed to accurately measure the in-plane motion of MEMS actuator. The performance of the proposed FLDV is evaluated in terms of signal stability and the measurable range.","PeriodicalId":187850,"journal":{"name":"2009 IEEE 22nd International Conference on Micro Electro Mechanical Systems","volume":"43 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":"131747694","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 system can be fully operated with a 5V DC voltage, and does not require any external air compressor or bulky power supply. The size of the whole system is 67 mm × 66 mm × 25 mm, and is smaller than a PDA cell-phone.

Each device is composed of an out-of-plane curved microtuft formed from laser-machined Kapton® polyimide and PECVD-deposited SiO2, and a conductive elastomer piezoresistor with a measured gage factor of 7.3 located at the base of the microtuft. The fabrication and performance of a prototype array and a fabrication sequence for large-area arrays on flexible substrates is demonstrated, for flow field mapping across an airfoil. The fabrication sequence also enables backside interconnects without adding further process complexity, which facilitates integration and enables the sensing of airflow with minimum interference due to the sensing circuitry.

Methods are needed to program the self-assembly process so that we can assemble heterogeneous components necessary to build a complex system. Here we present a new method of programming the self-assembly process which is based on optically removing blocking polymer from designated receptor sites. In order to perform the self-assembly process we need to fabricate free-standing microcomponents and templates. Templates were fabricated on both plastic and glass. We have shown successful assembly of four types of silicon microcomponents on plastic. The blocking AZ4620 resist was removed from the designated receptor sites immediately prior to the assembly of the desired microcomponents by using optical masks, UV exposure, and resist developer. 98% yield of proper positioning of microcomponents on a plastic template was achieved within ~10min of pipetting the components onto a template in a fluidic medium.","PeriodicalId":187850,"journal":{"name":"2009 IEEE 22nd International Conference on Micro Electro Mechanical Systems","volume":"43 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":"128026609","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 highly symmetric ball lens is achieved due to the lower gravity influence in liquid. The microlens' diameter is controlled by the volume of the dispensed polymer. Moreover, it is easy to dispense, form, and align the liquid-phase polymer microlens with MEMS structures while processing in liquid. Thus, the microlens can either be a discrete optical component, or directly integrated with MEMS structures during the process to form a SiOB (silicon-optical-bench). To date, ball lenses with diameter ranging 200¿m~600¿m and surface roughness ≪10nm are fabricated. A typical sphericity is 8.6¿m for a 525¿m diameter ball lens.

This latter model makes it possible to compute SiBAR performance parameters that cannot be obtained from the analytical model, e.g. the relationship between transduction area and insertion loss.
