This paper presents fluid manipulation using multiscale spiral-type magnetic machines with magnetic wireless operations. Magnetic spiral-type or helical machines have been widely used for biomedical applications. We considered two applications in the spiral-type magnetic machine: microfluid control (micromixer and micropump) and application for a pediatric blood pump. We investigated micropumping and mixing abilities by using the magnetic spiral machine (Φ ∼1.25) mm × 10) mm) in a silicone oil with a kinetic viscosity of 5 mm2)/s. In addition, we confirmed the ability to apply these to a pediatric blood pump based on large machine Φ ∼18) mm ×35) mm). The pump produced a flow rate of 1 to 3.5 L/min with a pressure rise of 40-60 mmHg.
