Abstract :
The diamagnetic levitation principle is used to design an innovative typology of suspension for energy harvesting devices applied to very low frequency vibrating environments. The static configuration of the magneto-structural coupling is investigated starting from the theory of magnetism and a discrete numerical model is finally developed. The experimental validation is provided with measurements conducted by dedicated samples with a diamagnetic proof mass levitating in a magnetic field generated by permanent magnets. The results presented in this work provide important indications to the designer of microsystems for energy harvesting and the modeling approach proposed represent a valid design tool for coupled systems.
