Abstract: Controlled motion capsules and associated systems and methods are described. Controlled motion capsules can decelerate, and stop, without damaging epithelial walls. If any components fail, a controlled motion capsule, without added energy, becomes its most compact shape, passing harmlessly through the GI tract. Controlled motion capsule may include a shape changing material, comprising a reversible soft copolymer, in a container in the capsule, with a nonionizing radiation emitter, and a controller to activate the nonionizing radiation to expand and contract the shape changing material, on detection of certain conditions or instructions. Expansion of the shape changing material, including contact with epithelial walls, decelerates and can stop the controlled motion capsule movement. Motion control allows scientists to study the microbiome, doctors to deliver intestinal drugs at precise locations, and to closely examine signs of precancerous growth.
