On 9-12 February 2025 Dr. Semih Sevim from ETH Zurich, represented the EVA project on the 2025 IEEE Conference on Advances in Magnetics at the Forum of Bressanone, Italy as an invited speaker.
In his talk, he present several approaches for effectively fabricating and delivering small-scale magnetic robots. The strategies involved the magnetically navigated tethered robotic tools to assist in delivering untethered magnetic devices to target sites, a method that offers a promising solution for the controlled deployment of untethered magnetic devices within the complex circulatory systems of the human body.
Moreover, he introduced novel fabrication techniques for creating highly integrated small-scale soft devices that closely mimic the complex motion and morphing behaviors of living organisms. By leveraging microfluidic control to regulate reaction-diffusion processes, he showcased the fabrication of multifunctional and compartmentalized magnetic soft continuum robots (mSCRs). Under controlled RD conditions, these mSCRs can be tailored in terms of geometry, stiffness, and magnetic responsiveness. Additionally, chemically cleavable regions within the mSCRs enable disassembly into smaller robotic units or roll-up structures when exposed to a rotating magnetic field, after being deployed with the aid of tethered magnetic devices.
The presented findings highlighted the importance of new deployment methods and versatile fabrication techniques in the development of highly integrated small-scale magnetic devices, bringing these technologies closer to real-world biomedical applications.
