Syringe-pill injects you on the inside

Biomedical engineers prototyped a pill that integrates a syringe to inject insulin into the floor of the stomach. From Science News:

The shape is designed to guide the device to rest, cap down, on the floor of the stomach. There, it sticks a needle tip composed almost entirely of insulin a few millimeters into the mucus membrane lining the stomach. Once the insulin needle tip dissolves, the device passes through the rest of the digestive system.

Thanks to the dearth of sharp pain receptors inside the stomach, the tiny injection “is unlikely to cause any discomfort,” says study coauthor Giovanni Traverso, a gastroenterologist and biomedical engineer at Brigham and Women’s Hospital in Boston and MIT.

3D printed origami robots that crawl and grab when activated by magnets

A team at MIT’s Department of Mechanical Engineering and Department of Civil and Environmental Engineering have created a set of foldable, 3D printed robots that are doped with magnetic particles that are precisely aligned during printing; when triggered by a control-magnet they engage in precise movements: grabbing, jumping, rolling, squeezing, etc. Read the rest
