In the question How strong is the electric charge capacity of Martian dust storms? the possibility of electrically-charged dust and its inconvenience or danger to Mars explorers is described. The triboelectric effect (commonly named static electricity) is described in Wikipedia.
Thus Mars explorers, re-entering their habitat or spacecraft, could find themselves coated in dust which until now has unknown composition. The effects of a Martian dust and its possible risks to health is discussed at length in What would it feel like to be in a Martian dust storm?
Would it be feasible to design a device to remove the statically-charged dust using an electric field? (Would a handheld device be more effective than a frame that a Marstronaut could walk through?)
