Specialists from MIT Media Lab believe that liquid drops can be used as a computer interface.
Engineers have developed a system that allows you to very accurately control the position of the drop on the board.
The board consists of a material with a low coefficient of friction. From above it is covered with a copper net. Managing the electric field of the board, specialists changed the direction of the droplet movement and its shape. The developers were able not only to combine the two drops into one, but also to separate it. Thus, you can create colorful surfaces on the surface, the authors of the idea believe. Now they are working on creating a mirror that can display messages in a fogged state.
