Summary:This paper presents an analysis of the magnetic force generation and the membrane displacements of a bidirectional electromagnetic microvalve for drug delivery application. The proposed microvalve contains two arrays of equidistant micro-coils placed opposite to each other and a permanent magnet (NdFeB) attached to a flexible PDMS composite membrane. This work is primarily focused on the design of the bidirectional actuator and the performance analysis of the magnetic force on the PDMS membrane, generated by the magnet and the coil array. The magnetic force that is displacing the PDMS membrane is 8.3 mN and the membrane displacement is found to be 400 µm.
