Abstract
The present disclosure provides for wirelessly actuated soft robotic undulating pumps designed to efficiently transport both viscous fluids and solid cargos in human patients, methods of manufacturing a peristalsis-producing stent, and systems including a pair of soft magnetic sheets and a magnetic actuator configured to produce a magnetic field which generates complementary undulation of the pair of soft magnetic sheets. In an aspect, the pair of soft magnetic sheets can have at least a first soft magnetic sheet and a second soft magnetic sheet, and wherein a magnetization profile of the first soft magnetic sheet is coordinated with a magnetization profile of the second soft magnetic sheet.
