An all-in-one wireless pump with a power generator was developed for use in biomedical applications. The developed pump is driven by an external rotating magnetic field. Thus, the performance of the system is limited by the magnetic properties of the rotor. To improve the magnetic properties of the magnetic all-in-one pump, a fully magnetic impeller was fabricated with magnetic powder (Sm 2Fe 17N 3) because sintered magnetic materials have a lower degree of freedom for shape. The magnetic moment (M) and coercive force (H c) of the fully magnetic impeller are 0.993 Am 2 and 0.82 MAm, respectively. We analyzed the magnetic properties of the fully magnetic impeller using simulation and experiments. In addition, we investigated the improved performance of the all-in-one pump system using the fully magnetic impeller.
