Using a planar sheath-flow geometry fabricated on a glass chip, we generated monodisperse organic droplets consisting of two differently colored miscible segments; these droplets were subsequently polymerized to form monodisperse Janus microspheres having both electrical and color anisotropy. Those particles could be used for an electronic paper application. We also engineered particles of geometrical anisotropy by using two immiscible organic fluids as the raw material. Multiple-channel integration for scale-up of productivity was also demonstrated.","PeriodicalId":250831,"journal":{"name":"19th IEEE International Conference on Micro Electro Mechanical Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115367840","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}

By hydrodynamically rectifying the particle positions inside the microfluidic circuit, particles suspended in liquid are perfectly aligned onto one sidewall inside the microchannel, and then concentrated and sorted according to size. We used particles with diameter of 1~ 3 μm; they were concentrated 30~ 80-fold, and separated even when the difference in particle diameter was smaller than 1 μm. In addition, it was demonstrated that the distributed flow rates well corresponded to the theoretical values.","PeriodicalId":250831,"journal":{"name":"19th IEEE International Conference on Micro Electro Mechanical Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115609804","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}

Using a laterally vibrating shaker table, we achieved a bidirectional motion by simply attached two polydimethylsiloxane (PDMS) rods with opposing saw-tooth shaped legs. These two parts have different ratchet density and leg height. The polymeric body was floating on a thin silicone lubricating oil 20 μm in thickness. While vibrated at a constant amplitude of 0.2 mm, the micromobile soft cylinder (2x2x20 mm3in dimensions) changed its motion direction at a cross-over frequency of 156 Hz. This cross-over phenomena is due to difference between the static and kinetic friction of the two opposing parts.","PeriodicalId":250831,"journal":{"name":"19th IEEE International Conference on Micro Electro Mechanical Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128804718","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}
