In　this　paper,　an　electromagnetically　actuated　tube　type　micropump　is　proposed,　conceptually　designed　and　experimentally　investigated.　The　micropump　mainly　consists　of　two　electromagnets,　a　NdFeB　permanent　magnet,　a　ball-valve　and　a　Teflon　tube.　The　reciprocating　movement　of　the　permanent　magnet　is　realized　when　the　two　electromagnets　excitated　alternatively.　The　liquid　in　the　tube　flows　from　the　inlet　to　the　outlet　while　the　permanent　magnet　reciprocating　in　the　tube　regulated　by　a　one-way　valve.　Maximal　flow　rate　of　208.75　mu　L/min　and　maximum　backpressures　of　539　Pa　were　achieved　at　a　applied　current　of　0.5　A　when　the　actuation　frequency　is　5　Hz.　Compared　to　other　micropumps　with　membrane　structure　driven　by　an　external　electromagnetic　actuator,　the　tube　type　micropump　is　more　reliable,　small　in　volume,　easy　to　be　fabricated　and　has　zero　dead　volume　and　less　turns　of　coil.
