Microrobots represent a promising frontier for the future of medicine. Although they are still in a central phase of their development, they are designed to be used in applications such as biosensors, minimally invasive surgery, targeted drug delivery, and diagnostics. This thesis presents an overview of the main design aspects of magnetically controlled microrobots. It will examine the choice of materials and structural design, which must ensure biocompatibility and be suitable for movement in biological environments characterized by low Reynolds numbers. The discussion will then move on to magnetic actuation systems, outlining the different types of magnetic fields and the devices used to control microrobots. Finally, after an overview of imaging systems, the potential medical applications of microrobots will be explored.
I microrobot rappresentano una promettente frontiera per il futuro della medicina. Sebbene si trovino ancora in una fase centrale del loro sviluppo, sono progettati per essere impiegati in applicazioni quali biosensori, chirurgia minimamente invasiva, somministrazione mirata di farmaci e diagnosi. In questa tesi verrà presentata una panoramica generale dei principali aspetti progettuali dei microrobot a controllo magnetico. Verranno analizzati la scelta dei materiali e il design strutturale dei robot, che devono essere biocompatibili e adeguati al movimento in ambienti biologici caratterizzati da un basso numero di Reynolds. Si proseguirà con l'esame dei sistemi di attuazione magnetica, illustrando le tipologie di campi magnetici impiegabili e i dispositivi utilizzati per il controllo dei microrobot. Infine, dopo un approfondimento sui sistemi di imaging, verranno discusse le possibili applicazioni dei microrobot in ambito medico.

Abstract
Microrobots represent a promising frontier for the future of medicine. Although they are still in a central phase of their development, they are designed to be used in applications such as biosensors, minimally invasive surgery, targeted drug delivery, and diagnostics. This thesis presents an overview of the main design aspects of magnetically controlled microrobots. It will examine the choice of materials and structural design, which must ensure biocompatibility and be suitable for movement in biological environments characterized by low Reynolds numbers. The discussion will then move on to magnetic actuation systems, outlining the different types of magnetic fields and the devices used to control microrobots. Finally, after an overview of imaging systems, the potential medical applications of microrobots will be explored.| File | Dimensione | Formato | |
