| 摘要 | A microfluidic pump composed of a cylindrical chamber, transfer ports having an inlet port and an outlet port positioned on the cylindrical chamber, a magnet member attached outside the cylindrical chamber, a magnetic piston in sliding communication with an inner wall of the cylindrical chamber, a magnetic material, and a valve member. The magnetic material self assembles to form a seal plug separating the inlet and outlet port, where the seal plug forms a link between the magnet member and the magnetic piston to rotate the magnetic piston along the inner wall of the cylindrical chamber, where a working fluid suctioned within the cylindrical chamber is discharged at the outlet port during a movement of the magnetic piston from the inlet to outlet port. The valve member positioned at the outlet port prevents the backflow of the working fluid towards the inlet port after the magnetic piston rotates past the outlet port. | ||||||
