Recent developments in minimally invasive medicine have been fomenting the development of smaller and controllable devices. However, one of the major challenges toward decreasing invasiveness of medical procedures is miniaturizing actuators to milli- or microscale while maintaining reliability. This is the context in which magnetic actuation surfac...

Flexible materials embedded with hard magnetic particles have recently gained widespread recognition as small-scale actuators due to their capacity to be a rapid and precise shape-shifting material. Strontium ferrite (SrFe 12 O 19 ) particles have been shown as a great candidate for such applications, since it is an inert hard magnetic material tha...

This article presents a novel algorithm to predict the shape and the support configurations of a magnetic robot acting like a supple beam which deforms due to an imposed magnetic field. The soft magnet loosely rests on a flat horizontal surface which provides the pivoting supports to the robot to attain its deformed shape. The key difficulty in ana...

Human hands play a key role in almost all activities of daily living (ADLs) because it is an incredibly versatile tool capable of complex motion. For individuals who have had a complete loss of the hand, the ability to perform ADLs is impaired. Effective prosthetics accurately simulate the movements of a human hand by providing a high number of deg...

In the past decades, wireless milli and micro devices have been incorporated into medical procedures as a way to reduce invasiveness. However, the commercially available methods still consist of passive locomotion devices, which is a limiting factor to the development of minimally invasive devices. Magnetism simplifies the design of small-scale dev...
