Resumen
Purpose – This paper aims to present a modeling approach of diamagnetic microsystems for design and optimization requirements. It is demonstrated on the stabilisation optimization of a diamagnetic levitation system for biomedical applications.
Design/methodology/approach – Surface approach was used to compute analytically the magnetic field induction. This modeling is depending on system to design (approximation, equation simplifications due to specific geometries) coupled with a design framework which is based on symbolic equation derivation and SQP constrained optimization algorithm.
Findings – Optimally stabilized magnetic levitating systems, for a pyrolitic graphite micro plate and for a latex bead.
Research limitations/implications – The analytical or semi‐analytical modeling of magnetic field induction and forces produced by complex geometries is sometimes either hard to establish or not adequate to perform a fast optimization, due to heavy numerical parts implemented into the device modeling.
Practical implications – Implications are of two kinds. First are results of the magnetic levitating system which can improve lab on a chip for biomedical applications. Second is design framework improvement with diamagnetic modeling capabilities.
Originality/value – Stability optimization of diamagnetic levitation system, based on an original approach of modeling and sizing with dedicated tools.
