**6. Conclusion**

It is not possible in the space available to offer an exhaustive overview of the applications of magnetic sensors in the field of medicine. We have limited ourselves to presenting just some particular works, that we have recently developed, some that are currently being developed and some that are still in the future.

It seems obvious that the development of magnetic sensors and actuators is generally linked to the development of magnetic materials. Furthermore, it could be said that the development of our technological civilization is linked to the development of magnetic materials. If this assertion sounds too exaggerated, please imagine the consequences of the disappearance of the silicon steel sheet and with it all the electric motors and transformers. Or just think about the permanent magnets inside all mobile phones, or the magnetic

This is even more evident in the case of the biomedical applications. The increasingly strict requirements for sensors and actuators in the field of safety, as well as for biocompatibility, corrosion, miniaturization, low consumption, etc. are impossible to meet without new magnetic materials. Just think that the fight against the most feared disease of our time could depend on something so simple (but not easy) as the suitable magnetic material.
