Abstract

Shape design optimization for an untethered microdevice meant to navigate in the human bloodstream is studied based on previous variational finite element (FE) work done. The suggested shape for a first generation prototype is a prolate spheroid design, which enables to minimize the drag force and to maximize the use of the MRI´s magnetic gradients
