Lubrication effects on droplet manipulation by electrowetting-on-dielectric (EWOD)
Ken Yamamoto, Shimpei Takagi, Yoshiyasu Ichikawa +1
Electrowetting has a potential to realize stand-alone point-of-care (POC) devices. Here we report droplet-migration characteristics on oil-infused electrowetting-on-dielectric (EWO…
Concentration-adjustable micromixer using droplet injection into a microchannel
Ryosuke Sakurai, Ken Yamamoto, Masahiro Motosuke
A novel micromixing technique that exploit a thrust of droplets into the mixing interface is developed. The technique enhances the mixing by injecting immiscible droplets in a mixi…
Initiation of the Worthington jet on the droplet impact
Ken Yamamoto, Masahiro Motosuke, Satoshi Ogata
Deformation of liquid droplets by impingement induces Worthington jet in certain range of the impact velocity. Although the growth of the jet as well as its tip velocity is predict…
Obtaining superhydrophobicity using commercial razor blades
Ken Yamamoto, Hideyuki Takezawa, Satoshi Ogata
Because the superhydrophobic characteristic appears by forming a composite surface consisting of solid and air underneath the droplets, a large number of rough surfaces that can tr…
