In this study, we introduce a practical improvement to our experimental method to measure the mechanical properties of small liquid droplets by observing their oscillation on solid substrates. Instead of the electric tweezer system used in our previo

In this paper, we introduce a method to measure the surface tension of a droplet on a solid substrate by observing the resonance oscillation excited by applying Maxwell stress using electric field tweezers in a noncontact manner. Additionally, we mea

An electromagnetically spinning (EMS) viscometer enables the remote sensing of rheological properties. To date, the distance of remote sensing of EMS system has been limited by the aperture size of rotating magnets, which drive the rotation of the me

Shapes of 30 micron-droplets floating on liquid surface are observed. When a microdroplet ejected from an inkjet nozzle impinges on the immiscible liquid surface, we can observe the stable shape of the floating droplet after 200 μs from the touchdow

Using ripplon spectroscopy, we observed the dynamic structure factor of liquid-surface displacement in a non-uniform state with a temperature gradient. The sensitivity of this light-scattering experiment has been considerably improved by employing lo
