摘要： A magnetic bead trap-and-mixer includes a channel having openings at opposing ends, and a rotor adjacent to the channel and comprising a permanent magnet, wherein the rotor is adapted to apply a magnetic field to the channel of sufficient strength to direct the movement of magnetic beads therein. In aspects, the channel is straight and/or has narrowed end. In further aspects, the rotor generates in the channel areas of areas of strong magnetic fields alternating with areas of very weak magnetic fields and the strong magnetic fields extend entirely across the channel.

摘要： A piezoelectric ultrasonic motor having 2-dimensional positioning movement includes a stator. The stator includes a piezoelectric ceramic bar and an electrode disposed on the bar. Each bar includes two wings that are separated by a predetermined angle to form a predetermined shape. A power source is used to apply a voltage to the stator to excite a bending mode vibration in the each of the wings, and the combined motion of the two wings produces an elliptical motion at a tip of the wing. A load is operatively connected to the stator, such that a portion of the load in contact with the stator is driven to move linearly through a frictional force between the load and the stator, due to the elliptical motion at the tip of the wing.
