The form factors of displays using fog or water surface are limited by our ability to control the non-solid substances used as the diffuser. We propose a charging technique for polar aerosols (e.g., mist or fog) that allows control of the shape and trajectory of such non-solid diffusers using electric fields. We report experiments that allowed us to design a charging mechanism that produces charged fog aerosols with homogeneous electrical mobility.
We illustrate our idea by demonstrating how electric fields can be used to control the shape of a fog display and the trajectory of a bubble display.
