Conventional force sensors, such as piezoelectric and beam sensors, encounter limitations in measuring droplet impact forces at extremely small length scales. Our proposed vision-based framework is qualified in digitizing the dynamic droplet impact behaviors and forces on non-conventional surfaces (tilted surfaces), extreme spatial and temporal resolutions (micrometers and hundreds of microseconds), along with a force sensitivity of approximately 10 pico-newtons.

We report a programmable curvilinear self-propelling of droplets based on the collaboration of the curvilinear wetting gradient and the Leidenfrost effect. This design achieves motion trajectory in a well-controlled manner as well as high velocity and long distance of droplet independent of the preset channel, all of which manifest their extensive practical applications.

AC electric field-controlled heterogeneous paired-droplet merging offer a wider range of the coalescence region and longer merging time than homogeneous paired-droplets, by which a rapid, additive-free, and on-chip fabrication of hydrogel microspheres is achieved with a wide range of concentrations in high monodispersity.

Aerodynamic breakup of emulsion droplets in a continuous airflow is a fundamental issue for many natural phenomena and practical applications. This study experimentally investigated the aerodynamic breakup of water-in-oil emulsions in airflow. The digital in-line holography is used to measure the fragment sizes after the droplet breakup. The presence of the dispersed droplets in the emulsions results in a higher apparent viscosity and promotes bag film perforation. These features further lead to different transition Weber numbers and fragment size distributions.
