    Abstract: The invention provides a microdroplet- or bubble-producing device that does not require separate through-holes for different liquid droplet/air bubble-producing flow channels. The droplet-producing flow channels are configured in a three-dimensional manner unlike in a conventional device where they are configured in a two-dimensional plane, and therefore the flow channels can be provided in a more high-density configuration than the prior art. In the microdroplet/bubble-producing device comprising slit(s) and the row of the plurality of microflow channels, the slit(s) is/are a continuous phase supply slit, a dispersion phase supply slit and a discharge slit, the plurality of microflow channels are configured so that the ends of the slit(s) and the two supply ports on both sides or the supply port and discharge port on either side are mutually connected, and at the sites of connection between the microflow channels and the slit(s), the dispersion phase undergoes shear with the continuous phase flow as the driving force, producing droplets or air bubbles of the dispersion phase, which are recovered from the discharge port.

    Abstract: A force sense presentation device that presents a force sense force by forming a dynamic quantity distribution on a skin of a person includes a plurality of stimulation elements and a controller. Each of the plurality of stimulation elements stimulates the skin of the person. The controller controls the plurality of stimulation elements such that a dynamic quantity distribution for generating a target force sense is formed on the skin. An interval between the adjacent stimulation elements is an interval enabling presentation of a spatially continuous force sense. The force sense generates a self-kinesthetic sense of the person.

    Abstract: The present invention provides a micro two-phase droplet generating device that does not require separate through-holes corresponding to a plurality of two-phase dispersed parallel continuous flow channels. The micro two-phase droplet generating device of the present application comprises a row of a plurality of microflow channels, liquid transfer ports, and a slit, and is configured so as to form two-dispersion phase parallel continuous flows at first connection sites between the plurality of microflow channels, in which a first dispersion phase flows, and the slit, through which a second dispersion phase flows. A continuous phase is fed to second connection sites between the plurality of microflow channels, in which the two-dispersion phase parallel continuous flows flow, and another liquid transfer port, which is preferably a second slit, downstream of the slit, and the two-dispersion phase parallel continuous flows are sheared at the second connection sites, whereby two-phase droplets, and in particular, core-shell or Janus two-phase droplets, can be generated, and a product can be collected from a discharge port.
