Sometimes certain Physical discoveries are necessary to push new inventions. This is the place to ask if some of these prerequisite Physical or Material Science discoveries have been made to help you in the creation of your idea or new invention.


I was wondering if there is anything like a grid with openings that can be actuated individually. I am looking to control a fluid flow passing through a grid and want to cut off certain regains but not others through geotine like valves. The resolution of the grid should be less than 1mm for each cell.

have this idea that I think I need electromagnets that are about 0.125in and a bunch of them that are in a line with a separation of.100in and I don't think really need to be that strong for its small. L
