| 摘要 |
The present disclosure relates to a electrical device(1) comprising an electrode arrangement (2) comprising a magnet (3), and an electrode (5), an electrically conducting movable device (7),movable relative to the electrode arrangement (2) and spaced apart from the electrode arrangement (2), whereby a gap (G) is formed there between, and a suspension (9) comprising a liquid (9a), a plurality of magnetic particles (9b) dispersed in the liquid (9a) and a plurality of non-magnetic electrically conducting particles (9c) dispersed in the liquid (9a), which non-magnetic electrically conducting particles (9c) have higher electric conductivity than the magnetic particles (9b), wherein the suspension (9) extends between the electrically movable device (7) and the electrode arrangement (2)in the gap (G), and wherein the magnet (3) is arranged to provide a magnetic field through the suspension (9) to thereby align the non-magnetic electrically conducting particles (9c) between the electrode arrangement (2) and the electrically conducting movable device (7) to obtain an electrical connection between the electrode arrangement (2) and the electrically conducting movable device (7). |
