Stroke is #1 cause of long-term disability and #4 cause of death in the US. Most of the patients are not treated in time due to unavailability of professional neurosurgeons on site. We have developed a ferromagnetic soft continuum robot for tele-operated and autonomous navigation and treatment of strokes. The foundation is the hard-magnetic elastica theory which offers a fast and accurate prediction of the large deformation of the ferromagnetic soft continuum robot.

There are emerging demonstrations that micro- or nano-craters engineered on polymer surfaces can enable enhanced adhesion. In the past, we have developed a framework for quantifying the suction forces produced by isolated macroscopic craters neglecting surface effects. In this paper, we take surface tension into consideration because it plays a significant role in miniature craters on soft polymers. We have derived linear and nonlinear elastic solutions for the elasto-capillary distortion in miniature hemispherical craters whentheyare demoldedfromthe template.
