Magnetic Field Analysis on a Novel Electromagnetic Actuator for Fluid Handling Applications
نویسنده
چکیده
Abstract: This work presents a novel electromagnetic actuation concept that aims at the conversion of electromagnetic force into fluid power to enable gentle handling of biomedical fluids through circular microchannel. This concept is tested successfully on a mesoscale model and showed attractive concept suitable for microfluidic applications. In microtechnology, planar microcoils that offer enough magnetic forces suitable for actuation purposes are required. For this purpose, simple analytical expressions that estimate for the magnetic field intensity at different parameters (current, number of turns and gap between two neighbouring turns) in a planar spiral curved microcoil are developed.

Electromagnetic (EM) actuators in space applications are not a new idea, but they are most of the time associated to low Earth orbit missions, where the on-board magnetic moment interacts with the Earth magnetic field. More recently EM actuators have been studied in the context of formation flying as a way to generate inter-spacecraft force and torque in order to control the formation geometry ...
