Free-space micro-optics such as micro-Fresnel lenses, rotatable mirrors, beam-splitters and gratings are implemented on a single Si chip using IC-like microfabrication processes. Self-aligned hybrid integration with semiconductor lasers are also demonstrated for the first time. The MOB technology realizes a microoptical system on a single Si chip and has significant impact on free-space integrated optics, optical switching, optical data storage, and optoelectronic packaging. free-space. Using this new technique, threedimensional micro-optical components can be fabricated integrally on a single Si chip. The Si substrate serves as a “micro-optical bench (MOB)” on which micro-lenses, mirrors, gratings and other optical components are pre-aligned in the mask layout stage using computer-aided design and then constructed by microfabrication. Additional fine adjustment can be achieved by the on-chip micro-actuators and micropositioners such as rotational and translational stages. With hybrid integration of active optical devices, a complete optical system can be constructed on the MOB, as illustrated in Fig. 1.","PeriodicalId":273283,"journal":{"name":"Proceedings IEEE Micro Electro Mechanical Systems. 1995","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126710258","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}

This is achieved by using our newly developed microflow MEMS systems that consist of both microchannels and distributed pressure sensors. Two type of microchannels are developed. One is a straight channel with a uniform cross section, and the other has a variable cross section with Venturi-meter-like transitions. It is discovered that gaseous pressure distributions in microchannels are not linear. Moreover, it is also discovered that transitions in microchannels can result in either pressure drops or rises depending on their geometry. The Navier-Stokes equation with slip boundary conditions has been solved to model the gas flow in microchannels with uniform cross-sectional area. It is found that the model (first used by Arkilic et al., 1994) can fit the experimental data. One interesting phenomenon found in both microflow systems is that the pressure gradients near the inlet and outlet are very small. Such a phenomenon, however, can not be explained by this slip flow model.","PeriodicalId":273283,"journal":{"name":"Proceedings IEEE Micro Electro Mechanical Systems. 1995","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132231559","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}

Planar microrelays were fabricated and mechanically actuated to investigate electrical contact attributes. Initial experiments revealed contact resistances to be lower than 20R (even as low as 5R) and contact current loads up to 150mA without degradation. The Young’s modulus and residual stress of electroless nickel films, determined using mechanical test structures microfabricated alongside the microrelays, were found to be 154 GPa and 89 MPa, respectively.","PeriodicalId":273283,"journal":{"name":"Proceedings IEEE Micro Electro Mechanical Systems. 1995","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133792387","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}

Actually, ultrasonic atomizers are rather smaller than other method, so that nebulizers which are handy to carry type use ultrasonic vibration. But they are to large for a pocket or an endoscope. We have obtained a fine mist with a first trial of surface acoustic wave atomizing device whose dimensions are pocketable size. This functional device is able to reduce the dimensions to mm-order as a system. The atomizer consists of a vibrator, a cover and a tube. The vibrator and cover material is 127.8\" Y-cut LiNbO, to generate Rayleigh wave, a kind of surface acoustic wave. The Rayleigh wave is the driving force of pumping effect and atomizing effect. The pumping effect is caused by the wave motion of the elastic material and viscosity of the fluid like an ultrasonic motor. The atomizing rate varied according to the driving voltage. The maximum rate was about 0.1 ml per minute.
